Flick's Chariot
02/15/20 at 15:14:34
 
Hello all, a short history.

Ever since I can remember physics has drawn my attention. Around 5 years of age, I was folding newspaper into boxes, stacking like bricks building walls in the living room of my parent’s small apartment. At 8 my favorite read was Edmund scientific catalog with visions of actually creating some sort of laboratory in my bedroom. In my earliest teens, when not in the woods with friends cutting wood, making secret hideaways, or enjoying berries and fruits from bushes and trees, I was at home building a table saw from a TV cabinet console. It was the result of my failed attempt of repairing the TV that was giving up by dad and the instinctive nature of making something that can be used out of junk. Heck, I remember making a working steam engine out of a tall #3 tin can. It worked until the rubber washer used in the piston swelled and seized causing enough back pressure to blow the #3 vessel. Mom was not too happy with the loud explosion coming out of the back yard! I remember sitting in 7th grade class, looking out a window at workers replacing the roof on a house that was a few hundred feet away. We did not have AC in those days at school so the windows were open and the sound of hammering was present. It struck me odd that the hammer sound did not match what the worker was doing with the hammer. I think at that moment my curiosity was set with the physics of sound. Over my lifetime, the curiosity has leaded me to many endeavors building personal speakers, audio systems, and listening rooms.

Fast forward to the turn of the 21st century:

My 3 beautiful daughters were just about to leave the nest, 2 in high school, 1 entering college. I was a maintenance manager for a local grocery chain that gave me the freedom and means to build a complete wood shop. The family room at home was a theater of sorts with 36" JVC tube and audio components to match. The front speakers were a set of refrigerator sized Cerwin Vegas and Radio Shack center with a custom sub. A set of Bose 901s complimented with Death Boxes filled in the rears. A Wicket One coupled with the vaulted ceiling made the .1 sub. I also installed some tactical transducers in a love seat facing the JVC tube. The sound system rocked the house. In hindsight, I think it was my way of preserving dignity amongst the opposite sex Roll Eyes

I needed to remove the system from the family room to make the room more presentable. The basement of the house was never finished so it was logical to move the system to a custom room downstairs. The height was not ideal. I was moving from a 13' high vaulted ceiling to 7' and less height. The thought of extending the height was entertained but dropped because of the cost involved and the need to budget funds for other parts of the basement. Hopefully this limitation could be overcome by shaping and sizing the room. Flick's Chariot was conceived and plans were drawn. Flick is an appendage of my last name given to me by friends at work.

The dimensions are Front 12’W X 20’D X Back 16W’

Two issues needed correction before building the room. 1) All electrical junction boxes needed placed in an accessible location as well as plumbing valves being the self supported ceiling span would be finished drywall. 2) A support posts would need moved to give space needed for the dimensions of the isolated room.

A steel beam being placed along side the wood beam. Notice the stacked of drywall, fiber board, and plywood. This was not done in a haphazard way. It was stacked to accommodate the installation once the walls and ceiling was built.

2X6 stud framing was used for the walls. The beams to support the ceiling are placed alongside ductwork and new beam. Careful consideration was given not to have any of the Chariot structure come in contact with any part of the house structure.

The Chariot as it looks 20 years after construction. The side and back inside walls are two ½” drywall panels sandwiched with one 1/2” fiberboard. The front wall is concrete earth backed block with furring strips spanned with foam board and covered with ½” drywall. The ceiling is ½” plywood placed on top the walls and wood beams flanking ductwork and steel beam. A fiberboard and drywall layer is added to finish the ceiling. Outside walls are skinned with two ½” sheets of drywall. Fiberglass insulation was added to the wall cavities as well as placed on top of the plywood ceiling. All seams and unavoidable contact points were either treated with caulking or foam tape. There are two doors custom built to match the wall structure. One leading to a storage area has cam pivot hinges and a gasket seal. The other gasket custom door is for access to the HVAC system.

The entrance door is a stock sound proof door that was purchased at Home Depot. All electrical fixtures are placed on the surface of the interior walls/ceiling. Three circuits feed the room. One home run circuit is used for the electronics. An oil filled electrical heater is used for heat. Air condition is not needed being that the basement is 75% under the surface of the ground and I spend most of my time outside during the warmer months.

Thanks

Exactly Donnie! I need to clear out some stuff. Good old fashion garage sale will be done this spring and is being staged to the left. Those shelf's are earmarked for the storage area via the door on the right. The storage area is full of a DJ setup that needs disassembled and re-purposed. Unless you know someone interested in a system that could entertain a thousand or so? Pardon my mess but brighter days are on the horizon.

The Chariot does meet my expectations. It can be used anytime at home without interfering with normal activity. During the day music can be playing at 90 db levels in the room and not be heard at all upstairs. In the dead of night, the sound can migrate upstairs but not enough to interfere with anyone sleeping or trying to sleep. There are hardwood floors upstairs which the better half will not be without. I tried so may times to get carpet without success. A heavy walker upstairs can be detected in the Chariot. In hindsight, the floor joist could have been treated but was not. Not a big issue anyway as it stands. My closest neighbor is about 150 away and if he plays his boom box outside it is way more disturbing inside our house than the Chariot. The outside walls of the house consist of 1" fiberboard, 3/4" half lap pine siding covered with aluminum siding. The inside walls are 1" plaster. Windows are insulated double pane. So much for construction details. Power source filtering coming up.

Growing up in an era when tube electronics were rapidly being replaced with transistors, unused tube radios/stereos/tvs were handed to us inquisitive kids. Most of  the equipment had seen better days and did not work. Actually, I am surprised my life did not end with electrocution as many times my hands where in the box, power on, trying to wiggle the right tube to make the thing work again. I did learn some good life saving respect for electricity when one of my adventures abruptly sent me across the room with my back hitting the opposing wall then sliding down to the ground on my arse! Dazed and confused, it was about that time the thought of making a table saw came to mind.
Anyhow, there was this one working radio we kept up in my cousin’s room that had an aux input we used to play 8 track tapes. The radio worked OK, but on one of our overnight tinkering sessions the FM radio seemed to become haunted with holographic music. We looked at each other in amazement and listened intently until falling asleep. We were totally disappointed the next morning when the FM just sounded OK again.
The quest began to find out why. Well it seemed to be a couple factors. A perfect FM signal being fed and amplified using clean AC. The airways were clear of electrical interference as well as the AC grid power during the wee hours of night.
Building the Chariot, it was one of my goals to supply the electronics with clean AC power within budget. Searching the internet produced an article written by Magnan Audio Cables, “Recommended Audio System Tweaks”. The suggestions presented seem reasonable and within means. Basically the filtering tweaks adding film caps between hot to neutral and another with neutral to ground all over the house to eliminate the grunge in AC supply. I did not like the idea of adding custom built modules to outlets as described in the tweak but believed running a home run power source to the Chariot’s audio equipment and adding the hot to neutral treatment to that circuit could be just as effective. The neutral to ground receptacle modules could be eliminated by adding the capacitors to different circuits at the breaker panel. 320uf of capacitance was added to the Chariots audio feed and 6 separate circuits were treated at the breaker panel. When complete there was a noticeable improvement with soundstage presentation and more detail (blackness). That was almost twenty years ago!
Along with my respect for electricity, I pursued a couple years of training in electronics and held jobs that required said training. Over the years troubleshooting, there has always been this nagging wonder of why neutral to ground voltages were present and the same always fluctuating. Well there are many reasons and surely many of you engineers can fill a book of causes. But the fact is it’s there, can not be eliminated, and causes inaudible/audible effects with sound reproduction. This led to the next tweak for the Chariot – Balanced Power. I used Jon M. Risch recommendations for balanced power. At a risk of speaking out my league this is what I know:
Using the center tap of a balanced AC transformer the tap reference is effectively at 0 volts; 60 volts on the sine wave upswing and 60 volts on the down swing. Connect the grounds of equipment to this reference point makes all the equipment ground at 0 volts eliminating ground loop cause of stray voltages. Connect this 0 point reference to earth ground shunts grunge lowering the noise floor.
These tweaks along with a new ground rod were added and silently served well over the years, I think! Often over the years, I wondered if that box next to my circuit breaker box was still doing its duty! Quite frankly, I forgot exactly what it did until now. More on that later.

Neutral to ground box with cover removed.

5 hot to neutral modules in a DAK switching platform. The two end modules were removed from the top of the DAK cover which dislodged the insulating tape.

Two months ago I was cleaning up favorites in a browser and clicked on an old Decware link. Since that time the audiophile spirit was rekindled creating a desire to finish the Chariot project’s detail abandoned 15 years ago. The Chariot has seen plenty of use since it's completion but the room was never really dialed in for the best music reproduction. As it stands, the room sounds very good with the Jordans. The last couple of months going thru the music collection totally enjoying it, I fully understood it could be further improved with added sound treatment.
I finally started by moving the home theater electronics to the storage room and hanging the LED TV on the front wall eliminating a 2' deep Metro rack. This would give better access to the music reproduction gear for tweaking. The Acoustic Handbook was ordered and consumed. A plan was starting to form. But…

Except for a few TV upgrades and the shelving on the left this is how the Chariot looked for the last 15 years.

After hanging the TV, there was a very noticeable change in the sound presentation. My feet stopped tapping, the presentation seemed dull, and I became too analytic. The music was not enjoyable anymore. I thought maybe removing the rack had something to do with it or the TV wall mounting? Baffling.
I have full intent of driving the system with one of Steve’s amps but his backlog will not fit my timeline this year. I may even build the Zkit1. A local guy was selling an updated Heathkit SA-2. I jumped on it and brought it home. It did improve the mid range but the music was just not fully engaging most times. I repositioning the Jordan’s and changed cables which helped somewhat.
Then it happened, a light bulb lit up between my ears, aha moment, damn it - kick in a butt, dumb stupid shit feeling when I saw Steve’s posted picture of the opened Zen Line Conditioner combining with the fact that I’ve been looking through old project pictures. By moving the HT gear to a different locating and powering it with the closest available plug which happened to be the protection circuit side of a UPS, I effectively eliminated 60% of AC filtering. The DAK switching base which all HT electronics are plugged into (the main reason it still is in the system) also house 5 modules of hot to neutral filter capacitors. Plugging into the UPS totally eliminated any AC filtering action from these banks with the Chariot home run circuit because of the noisy electrons in the battery backup device! It might have worked if a normal outlet was used for the DAK but probably not as well as being connect directly in the dedicated circuit.

The new location for HT electronics is in the storage room. The DAK is the catawampus bottom piece.

I quickly removed the modules from the DAK and plan to permanently mount them inside the Balance Power SU-2 cabinet. Temporary paralleled with the SU-2 the Chariot is sounding like it did before moving the TV. Even better! I attribute the addition of the SA-2 helped the increased refinement.

The proof is in the pudding! My better half happened to stick her nose in the Chariot just about the time I finished hooking the caps back in. The short video shows here involvement. Seeing her involvement tells me I’m moving in the right direction.

Back on track with refinement of the Charoit, a post from Steve set in motion another project to eliminate the Radio Shack center channel speaker. The RS center was a left over when the system was moved from the family room. It does not fit in the current scheme and has questionable voice reproduction. It use to nest in a custom subwoofer when used in the family room.
This video sparked my imagination of using the Tang Band T2-2136SA driver in a custom enclosure to replace the RS speaker:

https://decware.wistia.com/medias/x4d46vqe8s

A Parts Express order was placed for a set of these drivers with the recommend 80hz high pass filter. A sketch was drawn. Searching thru old gadgets and wood laying around produced enough to get the project up and running.

The result is very good already outclassing the speaker it replaced. It was designed to enhance the human speech range of 100 to 3000 hertz coupled with Chariot dimensions. Speech is much more clear than its replacement. Tweaking will commence as well as a finish to match.

Eliminating the center channel RS speaker with a wall hanging unit will give access to the platform on top of the DAC to continue the Charoit build adding a ZKIT1. Most all parts arrived yesterday. The Edcor trannies will arrive in a couple more weeks. Current production has a three week lead time.
I was hoping to get the board built this weekend but the move to silver solder changed my plans. I have 25 and 75 watt soldering irons. The 75 watt iron just has one huge tip and the 25 watt is under powered for silver solder. A new soldering station is on order and will arrive next week. In the mean time, the board can be populated and cabinet made.

Spent some time buttoning up the IP tranny adding 4 hot to neutral moduals and salvaged Isobar box(circuitry removed) with 2 isolated ground recepticals.

Sheldon Stokes DAC with the last hot to neutral modual added.
After 18 years I finally can call this DAC project complete! This was a kit supplied with the board, drawing, and parts list. The toriod tranny was hand wound and the case crafted out of 1/2" corian. It is a fine DAC and served well over the years. I finished installing parts on the backplate this weekend.

Awesome! The ZP3 is a fantastic phono pre. I recommend GE JG-5751 black plates in the first two positions, and a RCA 12AU7 clear top side getter for the third.

The latest views of the Chariot. I've have since added a ZSTAGE, set of low pass NE5532 preamp boards to the AKSA amp, and 6 PE project boxes for capacitor modules(mounting the capacitors in the SU-2 cabinet did not play well with the tranny  :( ). As you can see, the room is less cluttered. Room treatment is the next single most bang-for-a-buck improvement that is in the planning stage. I am going to start with 40 square feet of P13-12 diffuser panels placed at the side, front, and back surface reflection points. Absorption panels will be better for the ceiling points because of height restrictions in the Chariot.

I mentioned above that the SU-2 balanced power transformer did not play well with the hot to neutral capacitor banks. It seems that orientation of the components matter very much to the point that the interaction of magnetic flux and capacitors can create a circuit that draws current...a lot of current! When I placed the capacitors on the board on top of the SU-2 there seemed to be no problem. When the capacitors were mounted inside the case it conducted 7 amps without any load. I only found this out when adding the AKSA in the circuit for use as a sub amp. This caused the overload to initiate. It was pulling 14 amps with all equipment running! Normally it would be 6 or 7 amps.

I purchased some project boxes and and dug up TV power cords along with extension cord ends to make the modules as shown. Now, all is well with the capacitors plugged into the dedicated outlet.

New hot neutral module scheme.


Temporary setup after capacitor removal from SU-2 case.

I got some time on my hands and found out how easy it is to post pics in the subject body...so excuse my rambling Grin

After calculating a parts list for the 1312's, I quickly realized that using hand power tools would add up to self abuse. So I am waiting for this guy to come home from work to pick up the single best stationary tool for the job. It will also come in handy for another project in mind.

Yes if you use a file sharing service it opens up all kinds of possibility's.

Also if you want to attach a photo that you see on the internet, just right click on the photo and copy the image address.

Then hit the insert image icon and hit control V and Bob's your uncle, you got a picture in your post, or multiple pictures.

What Donnie said on posting pics.

I picked up my new 1968 Craftman saw. Spent the last couple of hours cleaning her up. She is a diamond in the rough! The extras are just gimmicks...especially the sabre saw attachment. The past owner and I had a good laught talking about that attachment. She is tight and cuts square. What more can a man ask for.

The radial arm saw has come to be an invaluable tool for Chariot updates and rekindled my desire to have access to a complete maintenance shop. I spent the last 8 months converting my garage into a very versatile work center. I built, among other things, diffusers for the Chariot.

I posted about the P1312 diffuser build here. https://www.decware.com/cgi-bin/yabb22/YaBB.pl?num=1607031346

Since the build, the forty P1312's were stacked flat(live edge serving no purpose but stability) on a side wall of the Chariot.

I received over a hundred LPs from my son-in-law this past spring and got the urge to give the vinyl a whirl. After about going through half of the albums, it dawned on me to make use of the diffusers to see if there is an ultimate position in placement.  I proceeded over the last month positioning the diffusers at various locations in the room. It turns out that some placements had little effect on the sound while others profound. This exercise gave me more insight on the workings of the room with sound.

The construction of the walls in the Chariot aids in the softness of the room except the front wall which is backed by concrete block. The ceiling for the most part aids to the warmth except the middle third which has metal duct work above. The concrete floor with thin carpet and pad adds to the hardness of the room.

The placement of eight 1312s flanking the first side reflections toward the sweet spot increased intimacy with vocals and broadens the sound stage somewhat. This placement also added detail for the high end of the home theater system.
Stacking the remaining thirty two 1312's two feet out from the front wall basically did nothing. Maybe increased the sound stage a little.


Moving the diffusers onto the floor in the area below the ceiling created more mid/low bass to the point of not needing sub augmentation with the Jordan speakers. This also made more apparent the transmission line configuration of the speaker system which reinforced my desire of moving to open baffle.


Moving six diffusers from the floor to directly behind the sweet spot was the most profound to date! This increased the soundstage wide and far. Detail increased to the point of unveiling information. For example, Holly Cole's version of "The Tennessee Waltz" on the "Don't Smoke In Bed" CD always struck me having a flaw about a minute into the track. Where she sings "my friend". Turns out after my placement of the 1312s, the phrase is a second dub of her singing at a slight delay. Maybe still a flaw or her heated subconscious of the situation.


The use of the 1312s is giving me great insight of the workings of the Chariot. I am now formulating a plan to completely finish the sound treatment of the room using mostly materials laying around. Including shavings from planing oak! Stay tuned.

Comments?

John

That door with chair art weights well over a hundred pounds. When first installed it worked well until a failed sump pump swelled the jamb and door. Had to reinstall it after rework. Then the AC condenser pan rotted out. Repeat. Hopefully no more issues arise. The door seems to get heavier with age Wink

It is hard to believe it has been a year since posting updates about the Charoit's journey! There has been a lot accomplished over a years time. The CD racks were moved to the side walls, a CSP2 was added, new silver interconnects and silver plated 8 gauge speaker cables, 10 gauge power cables to all equipment, and some tube rolling. Sound treatment including both absorptive and diffusive have been added to all surfaces. Bass treatment was added to the rear corners. Front corners and ceiling coves will be tackled sometime in the future.

I took some time to catch this treads progress with a video. The track playing by Loreena McKennitt is very bass heavy and over the years it is improving in the Charoit. Sign of progress Grin

https://youtu.be/vY2u8cj9n28

The latest addition of a point-to-point build is in motion.
A tread was started on the build. Can be view here:

It has been a while since the last post. Some progress has been made in the charoit. The Otari found a favorable placement on the isolation stage. The Wicked One is now being used as a sub for the Crystal 10s. The couch was replaced with a lazy boy recliner. A thousand or so vinyl, tape, and concert DVDs have been placed for culling.

Spent a day cleaning out the audio graveyard(storage room). Ended up placing the 18hz subs from the DJ setup in the listening room. Powered with the 350 watt plate amps set 180 degrees out of phase the subs add that feel of subsonic frequencies to the music that has it. These may become a permanet fixture in the room. It is starting to look like some other prominate room in this forum Smiley

That be it, Kamran. Going to make a couple of oak side panels to replace the stock black plastic laminated ones. The oak ones will tilt and bring the 5050 up to a workable seated height but not too much to hide the center channel HT speaker.

The latest acquisition found on a family farm that was purchased new by the family great grandfather in 1928. The granddaughter wanted it to go to someone that would appreciate and use it. The motor runs good but sound box needs rebuilt. Heck, anything this old needs a complete service overhaul to last another century. The cabinet shows its age but solid without any lamination issues. I been looking for a Victrola Orthophonic for a couple months weeding through junk. This unit is one of the most popular units ever produced by Victrola. Its is also at the apex of Victrola's history before the power amplifier proliferation. A great find with minimal outlay!

Edited:
Added some horn detail pictures and did some much needed editing. Sorry for the poor read folks. I just was in a hurry to jump on the bike yesterday and excited to share my latest adventure here.


Thanks Tony! It has really progressed to my liken the last year or so! It does seem that one step forward causes some pause adding one step back.

Let me explain 🤔

I've been bitten by the Victrola bug. First with a purchase of a 1920 table model that was in shambles. Toiling with it gave a new appreciation of early american woodworking craftsmanship and horn design. Horns always attracted my interest as well as the calming effect of tooling wood ending with usually a beautiful eye pleasing product. Once the 1920 model was repaired, I ended up with a good understanding of Victrolas history and access to suppliers that had the necessary parts for the table models repair.

That led to my next purchase of a 1924 Consolette that was in a little better shape then the table model but still needed parts to get it working properly. The attraction for me was it had a orthophonic sound box with a larger horn which simply means a better frequency response of about 150 to 3000 hz! That is about it for frequency range of these old players.

The horns for the above mentioned models are basically a straight curved design that use the little knowledge known about horns back in the early 20s but showed improvement over time in the learning process.

The ultimate in Victrolas horn design before RCA bought the fledgling company in '29 was the Credenza with it's folded horn in a cabinet that when unfolded measured almost 7' in length and kept a true tapered form without sharp corners. The larger horn got the low end to just below 100hz but the high end also dropped because of cancellation created when higher frequencies traveled thru the lengthy horn. Just had to have one of these! The search began.

Interesting note is the lids on the other two Victrolas have a notice to close the lid while playing but the Credenza does not. I think it is related to the long horn and desire to get a higher frequency response by adding the little bit created from the needle, soundbox, and articulate upper horn by leaving the lid open.


Two candidates showed up in Facebook Marketplace. One was a eastern five hour drive away and the other a short western 30 minute commute. The closer one was in fair condition while the other was in good shape. I had a long chat with the guy who owned the nicer item but logistics was not in our favor. The person with the other one was not very communicative and my offer was ignored after limited messages. At this point, a decision was made to just be happy with the two in my possession even though logistics seem to become less of an issue with a new car purchase. The biggest new stumbling block was placement in our home. It became a real challenge. Even though I gave up on the purchase the feeling of incompletion lingers.

Like a stroke of lightning a message was received from marketplace by the person with the closer Credenza that stated a willingness to give it up for free. She said just come and pick it up! Blew my mind to instant mobilizing. The unit would fit in the new compact SUV. Gathering a few tools I left in a hours time. She opted for a porch pick up with no provided help. I wrongly thought that by removing the motor(electric)/platter assembly it could be placed in the back of the SUV by myself. The Consolette was manageable doing that. Well, when pulling up to the front of her house the Credenza was magnificently set at the top edge of 6 or so steps leading to the porch. It was an impressive sight and foretelling of the need for another set of hands to get it loaded. With a 4 way screwdriver, I disassembled it completely(except for the horn structure) while waiting for help to arrive.

While waiting, the lady came out and we had a good chat on the history of the Credenza that was her mothers. Indecision on her mothers part of letting it go caused the delay in response to me because it has been in the family since new. The daughter wanted to give it to someone that will take time for restoration and asked for a video when complete.

Oh, the misses claimed the Consolette for her space in the living room. There is a corner in the living room that sported a floor lamp and she pointed to that area and said "that Consolette will fit there." I was kind of shocked that she would want it in her proclaimed space but happy nonetheless. So it all worked out to fit at home. She is playing it now as I post this.


The Credenza at home in the Chariot. When recieved the motor did not work, the horn support bracket needed replaced(common on most Victrolas), air cylinders for the lid needed rebuilt, and it needed completely cleaned of coal dust. Three days of of work and $122.50 for parts and help got the Credenza up and running well.


Picture of where the sound is split at the end of the cast horn. This is where the horn wood craftsmanship begins. Constructed much like a barrel to form a exponential horn. The little thing hanging in the upper right might be a problem where the horn might have lost it's air tightness. Will have to take a closer look in the future.


Opposite view of the cast horn mouth from inside one of the split horn chambers.


View of the final split in one side before entering the final chamber as picture with the Credenza in the Chariot without a grill cloth.

Hey John,

The Chariot is looking better than ever!!   Love the recent acquisitions..especially the Otari !!  I couldn’t help but notice your white ZP3.  Boy how I would love to complete my system with a white topped ZP3.  Hint hint hint!! 😉. It goes without saying that if you ever decide to part with that ZP3 and upgrade…please let me know.  

Speaking of tape… one of my co-workers brother used to have a tape machine that is no longer being used.  I don’t know what make it is, but I’ve been bugging him to ask his brother if he wants to sell it.  Adding a tape machine would really be the icing on the cake.  

Keep the updates and the progress coming.  

Dom

For sure Dom, how could I not keep the updates flowing. I suffer like some of us here with less passionate local audiophile folks that appreciate quailty music.

Might have to will the ZP3 to you Grin

Once bitten with tape there is no turning back. Good luck with your acquisition.

I would make sure that ZP3 stays in pristine condition if it was willed😁.  I know the tape machine is the like holy grail, so I’m really hoping it will materialize.  Looking forward to the future updates and acquisitions.

Got around to make a video for the past owner of the Credenza in action. Refinish will have to wait for a winter project.

Hey John…..what a vintage sound!!  I can only imagine how much better it sounds in person.  Once you start refinishing the credenza, please keep us posted on the progress.  

What song were you playing?  I tried using Sound Hound but it it didn’t pull anything from the archives.

I think that there won't be much sanding refinishing the Credenza.The walnut veneer is around 1/16" thickness and all the trim is solid walnut. A good set of cabinet scrapers and a little finish stripper will do.

Shot of the 10" RCA shellac disk side played in the video.

Awesome. Thanks John.  Qobuz does have the artist, but that song didn’t pop up. Going to have to dig a bit further, and maybe check Tidal.  

Sometimes a piece of vintage equipment is best to be left in its original state…minus a clean up.  Either way the player is a great piece.

Thanks guys.

I think that the Consolette will get a refinish first(misses already hinted for that). Depending on the outcome the Credenza which has higher value might follow.
