Thanks Chrisby,  I knew many people used SS sub amps with their Tube main amps but I had never heard whether it sounded good or bad.  I am glad to hear I was wrong to assume it must sound bad.  I always like to save money.

Brian:  I'm sure lots of folks would argue against it, but my point was really that the power requirements for a sub amp usually dictate either large power supply transformer and substantial heat sinking with SS devices, and/or even larger iron and PP if tubed.  

Potential parts cost notwithstanding, there just isn't a lot of space in the 6x10x2 format of the plate series that Steve is proposing.  Of course the ZenMaster would be best to answer that question

Brad - that's a lot of wire, connectors and solder points for a
"purist" device.   Grin Grin  

But seriously, our friend Ed has recently got his-self excited all over again about the CG buffered passive "pre".  That might worth a serious listen - a whole lot less money than any TVC and just idiosyncratic enough to appeal to a lot of us.

chrisby,
 The signal only passes through one wire at a time.  There are multiple wires because the transformer volume controls "autoformers" are basically just multi-tapped transformers - one wire per tap.  When adjusting the volume know you are basically just switching from one set of input taps to another.
The desing is quite simplistic, though building it looks not to be - that's allot of soldering!  

In total the signal passes through connectors, the volume switch, some wire, and from the input to output tap of the autoformer.  No resistors, no capacitors, no tubes.

Btw, besides S&B, Sowter seems like a mfg'er making good attenuation transformers (TVC's), though like S&B they are not cheap (~$150ea) ...

http://www.sowter.co.uk/attens.htm

... and another rave review thereof ...

What about venturing into pro audio and offering Zen plate Mic preamps?  I'd love to be able to make a Zen recording someday.

Ya know what I think would be really really cool for us tinkerers.  What if you made plates for various stages of an amp, say a input, a driver, then an output, and a separate power supply plate.  What a guy could do is sub values of resistors and caps for various tubes used, say you like a 6SN7 as an input tube better than the 6922, change a few components to make it work, and you have it mated to a SV83 SET output.  Or say you wanted a push pull output for more power, you could connect this to the existing stages and have a drop in output replacement.

Another plate amp I would like to see happen is a active crossover, of two and three way.

I have seen amps build to where you could change out tubes and set switches and your off, what I am proposing is more like a plate set where you switch out plates and hardware it together.  Like one chassic three plates.

One think I like about separate power supplies is that you can mod it to death and make it as beefy as you want.

Hey steve. do you have plans for a 5 channel line stage pre. I think this will satisfy the 5 channel HT users out there. if you can, you can just build a 3 channel version, so we can purchase (1) 3 channel plus (1) 2 channel to fit our needs.
I for one believe that there is a sonic difference between just connecting your HT Pre amp directly to your Amp VERSUS putting in a line stage between pre and power. now, most of the HT users uses SS gear, this "add one" is a refreshing idea and may really improve the dynamics and impact of the system.
just my 02 cents

Found another source for DIY TVC's ... Wish I could pull all these TVC msg's to their own discussion thread.

http://www.audio-consulting.ch/DIYPot.htm



btw, forget the Antique Sound Labs Passive Ti (tvc based) preamp, at least for your MAIN system.  While it's good sounding for the money, and would be good for an intro or budget system or for a second/bedroom system, it DOES NOT sound better than the ZTPRE - which is probably no surprise. I've been listening to one I picked up on Audiogon with my Sony DVP-NS999ES SACD player and the SV83M amps.  

Hovever, I don't think the ASL Ti is necessarily indicative of the TVC idea/technology, and it's potential, on the whole.

A vacuum tube audio amp for my television is what I would like next.  I believe it ought to be monophonic to avoid creating soundstage events off screen, disconnected from the picture.  A mono version of the SE84c may fit onto this new plate chassis, I don't know.

-How about amps using 845, 572, or 833A, tubes? Muscle madness.

-A tubed output stage for the the Behringer:
 -ULTRACURVE PRO DEQ2496  This would make the ultimate DAC, allowing digital room correction and e.q. I am buying one of these one day, tube output stage or no tube utput stage. Read about it here: http://www.behringer.ca/02_products/prodindex.cfm?id=DEQ2496&lang=eng
-ULTRADRIVE PRO DCX2496  For those who want to bi, or triamplify.

Or how about a simple tubed DAC with AES/EBU and Digital coax imputs.  That way guys like me could use it on the Behringer stuff and others could add it to their favorite transport. The Art Audio DAC might be a good building block.

Thanks

How about a simple Push Pull amp based on the SV83?  Or a SET amp using the Svetlana 6AS7?  I have often wondered what this tube would sound like in a SET amp, no one is using this tube like this that I am aware of.

Don't know why I didn't think of this before...

Please build a low cost power conditioner!
It will improve the sound of all components and the whole system.   I mean, what good is a world class headphone amp without clean power? ... you'll just hear more of the grundge! Smiley

Maybe make separate circuits for each component -
cdp, pre, amp - assuming the conditioning needs for
said components differ.

Steve's principles on product development appears to be quite simple: He'll only market it if he thinks he has a chance of it being the best at that price point. It's a very reasonable and admirable one I guess and it's demonstrated by the absence of a Zen turntable. Another example is in the ZSLA1 instruction manual regarding line conditioners:

"To date the only line conditioners we know of that make a profound difference are made by PS Audio." My guess is that if he were to develop a line conditioner the PS Audio would be his performance aim point. My hope is that he'll be able to achieve that at half the price... Cheesy

How about a tube amp that matches the zen but has a high dampening factor so it can be used on the woofer section in a biamp setup.

With the right drivers the Zen should have no problem driving the woofers in a biamp setup.  Adding copious feedback to increase damping would take away a lot of the zen magic.

A "hybrid" Zen amp with SV83 tube based channel for the mids/highs and a Tripath Technologies "chip amp" for the low end.  It would have a built in active crossover of course with the normal adjustments, phase, level, crossover, etc.
The objective is to get some slamming bass with good integration but not touching the sound of the Zen mids/highs

This comment is interesting even though we don't know the context of his opinion. Speakers, previously owned amps, etc....

"A good tube pre, feeding a Tripath amp gets everything right, musically correct,zero even order distortion, and the 12AU7 getting all the sonic goodies just right, while still retaining the magic,with no tube hassle. All of the good, none of the bad... Best combo I have yet owned."

http://java.audioasylum.com/cgi/m.mpl?forum=amp&n=41679&highlight=griffin&sessio...

We've heard the "tubes are dead" cry before.  However, I would think its worth investigating.  You never know where those "Zen" discoveries will lead you. Smiley I hear you can get free chip samples from Tripath.

So we are looking at these options

Headphone amp
phono preamp
sv83 PP amp
Sub amp
Mic preamp
line conditioner
tube dac

I may have missed one.  I personaly think the phono pre, headphone amp, or a DAC are the best ideas.  Mabey we should put it to a vote

I'm new here, so maybe I'm off base, but a phono amp w/ standard mm 47k input; required gain (40db?- probably requires 12AX7's?); 2v output; optional volume control for those who want to drive an amp directly.

2nd choice (while I'm at it  ;D) a tube dac; 2v output; again- optional volume control for CD-only guys.

Make 'em look just like Plates (and/or CSP's).

3rd choice (hell, I'm on a roll here  :P) a line router with 4 inputs and 2 outputs (MAD has one). Imagine: Phono on input #1; Tuner on input#2; Tape Deck on input #3 (yeah, tape deck  :o); and CD (or dac) on input #4. Then on output #1: your Plate pre or CSP); and on output #2: your headphone amp or a line to your tape deck. (output switchable)

What about it?  

(this is fun..)

I wish the plate had not increased in price so much. $250 is much less of a DIY venture than $380.  But I guess good sound is for the well funded. I'm wondering what part(s) experienced that dramatic of an increase.

Weez,

At one point there was a "no brainer phono preamp" on the bleeding edge of release along the lines of your wish list, which is along the lines of my wish list, also. ¡Yo quiero!

I'm not sure if it was a plate project or not, but the idea vanished, like a midsummer night's dream.

I hereby revive that dream.

If a headphone amp fits on the same chassis as a CSP; one would think that a phono amp would fit also.

Maybe it's difficult from a noise standpoint?

I wish for a ZenMic pre kit.  Because of budget constraints many people who have project studios at home use one of the many cheap ($40-$200) micpre's that are out there.  A lot of these units that do have a tube in them often sound like crap when the gain is turned up or they add a bunch of noise (or both).  A single channel, balanced (XLR) ZenMic kit would be a big hit with both home and pro recordists.  Phantom power would be nice, a good VU meter would be useful, and a unity setting could be helpful for inserting into effects loops.  With such a huge market in the recording business I can see this unit easily becoming Decware's primary product if it is as high quality as everything else that you guys make.  I'm sure that once word got out professional studios would buy them up like hotcakes.  Such a product could put Decware on the radars of a lot more people out there.

I bet the proposed *no-brainer phono-pre* was transmorgraphied into the new ZP3 phono stage. And, by the way, if the ZP3 is better than my older version ZP.1, then it's a heck of nice phono stage!

A nice plate project would be an active tube x-over for subs Wink

as I am currently wraping up my ZKIT1 I will probably move onto the ZSP1 so I have something to compare to my current setup.

I am seriously looking for a DAC, I don't care either way if it has a tube output stage or not as price would be the biggest concern. Inputs would need optical and digital, usb would be a bonus but not required as I rarely have a pc in my listening area. I've been digging through the DAC kits that I've found online and they are all over the place price wise, more research is needed I think.

Phono stage, I'm very interested in this, I've been looking at tables lately as the wife has a rather large collection that is just collecting dust in her parents attic. So this is almost definitely on the list most likely around the end of the year.

My ZKIT1 is finished an OMFG is it awesome, I've been thinking about it, ZSP1 is most likely next, but truth be told a ZSP1+ that had 1 aux input and a phono stage... I'd be through trying to decide if I will take the plunge. If That became a reality, you would have to sign me up.
