Hi Lonely Raven,

I'm sure that your Mystery Amp will sound fabulous.
Congrats to you on your free Red NOS caps upgrade. Smiley

The waiting period will also have to include additional burn in of the new tubes and equipment.
I was fortunate to have a ready set of seasoned tubes for my CSP3, so I could enjoy the sonics of the New preamp immediately.

For my Torii MK4, it will probably take me another 2 weeks of normal usage before I can reliably judge the sonics.
It is likely that I'll just skip my originally planned tube-rolling experiment and just pop in my NOS GEC Gray glass KT66.
I trust Steve's judgement when he says that the KT66 is an upgrade over the EL34.
I'll just keep my metal base NOS Philips EL34s as a backup.

Dear Marky,

Maybe the Mystery Amp MK2 version will use EL34s?

I'm keeping my fingers crossed.  ;)

you can get identical gold plated knobs at goodcomponent.com. you simply have to widen the hole from 3/16" to 1/4" with a drill.

In case anyone is thinking of adding their own control knobs to the input and output adjustments.

The new CSP3 solo input tube is located very close to the 2 input adjustments. It might create difficulties in changing the input tube if you install any extra knobs.

In my case, on a new CSP3, the virgin tube socket is very tight.
Coupled with my large palm and fat fingers, I already have a slightly harder ( vs the CSP2+) time changing the input tube.
I therefore prefer to leave the input adjustments as they are.

LS,

True, but as long as you stick to knobs that are no larger than 1/2" diameter, it's still usable. Too bad Steve wasn't able to allow more space between the input tube and three control shafts. I guess the circuit layout underneath, the dual headphone jacks and input selector toggle pretty much dictate cramped controls under the circumstances. Sad

Hi Rizlaw,

I'm definitely not cut out to be a brain surgeon. Wink

I had a rather hard time installing the input tube without trying to knock the fragile glass side against the input control shafts.

For this reason only, I prefer the spacious layout of the older CSP2+.

Rizlaw,
I hope your wrong about the 1/2" diameter on the input knobs. I just received some knobs from parts express that are 3/4" in in diameter I figured I'd be able to get by with 3/8" from center of input shaft. Maybe I figured wrong. I guess I'll have to wait to get my CSP3 back from the shop to see if they will work. I guess my next try on knobs may have to come from Germany. Banzai music has some really nice knobs but  a lot of them are larger than 12-13 mm so it may also be a challenge. They have a few metal knobs that may very well work though. Here's a link:



Here is a volume knob that really would look nice on the black top of the CSP3. But diameter again maybe a problem just a bit over 3/4".


If you guys have a good source for knobs other than parts express please post it.

Thanks!

Cool



Sorry will not let me post links till I have 5 posted messages. Check out Banzai Music of Germany.

Funch

     Thanks for the link. There are a bunch of knobs here. Should be able to find some thing you can live with there.


Cool

Digger,

I use the ML's on my 2+; 1" for volume, and four half-inchers
for input/output trim. If I had it to do over, I would probably pick
knobs with lines on top instead of dots. FWIW

My ruler measures just 1/4" space between two of three 1/2" diameter knobs I have in front of the CSP3 input tube. This is just enough space to get my fingers on the top of the knob to turn it without touching the tube or the other knobs. If you have bigger fingers, like Lord Soth mentioned, you might be hitting and jiggling the hot tube from time to time. I think the 3/4" diameter knobs would come extremely close to the tube making it that much more difficult to turn. They might even touch the tube.

Rizlaw,
Here is what I found with the knobs that I purchased from Parts Express. Not to bad of a fit. Now saying that I don't have large chubby fingers so it may make a difference. The cost was a buck a piece for the input and output knobs the cost is 4 bucks for the brass gloss black knob on the volume control knob plus shipping. I wasn't sure if they would work after your post but these don't look to bad. My file sizes are to big to attach pics I guess and I'm not computer savy enough to reduce them. Anyway if you would like to see the pics just drop me an PM and I'll send them direct.

They actually do look pretty good on the CSP3.

I picked up two wood lathes this summer, one vintage one I'm restoring, and one modern one. Once I get them figured out, I might try my hand at making some knobs for our amps if anyone is interested.

Lonely Raven,
If you get around to making some for yourself post pics of them. I may have an interest in one for the volume position. The basic black knobs I have on my input and output look pretty good and also have a fairly low profile that doesn't distract from the overall appearance of the CSP3.
