as usual, Allynmey --

Congratulations for this superb amp Allyn!

What brand of pot are you using?

[Allynmey]

I use PEC 2W pots. With the later 'wrecks and some repairs I saw that he did he used PEC. The Komet Concorde uses PEC's as well as a proto or two I saw of Kens that used PEC. Maybe he likes them? Who knows? I think most of the stuff he used was due to availability and most of the mojo talk is BS for what it's worth.

[riscado]

are PEC pots similar to the ones being sold under Alessandro amps brand?

They look very similar.

[gearhead]

If you get a chance, read the interview with him in one of the amp books (name eludes me, but I got it somewhere).

Ken did indeed use what was available, and modified/tweaked the design/build to suit if the different parts made a difference.

Yes. Alessandro pots are PEC's.

Thanks for the pics! Very cool build as usual

Aren't the PEC pots stainless steel? Did you have any trouble soldering the buss bar?

[Allynmey]

You can't solder to PEC pots...and expect them to work properly! SS doesn't take solder well at all! I use Clarostat buss clips. They go around the pot and shaft and give a lip with a hole in it to slide a buss bar through. Works great! Wait...did I just say that?!

Allyn, I tried to figure out the Clarostat buss clips from the guts picture you posted, tough to see in such a small picture.
Would you have a link on where to buy them?
Or may be can we get them via Ampbuildersparts?

[skyboltone]

Nice, real nice

Are those boards/components the same dimensionally as Francesca?

Skyboltone; UR12 built some boards based on Francesca's perf, which has holes that are .265" (on center) apart. I can't seem to see his previous pics (with turreted but unpopulated board) at:

but if not, count holes with the Francesca shots. Or someone else will chime in

Thanks Gearhead.

You are the MAN Allyn!

I'd also like to know where I can get them.

I wouldn't suggest ordering from ampwares but i think they have them and here is a pic of the part in question from another company I haven't dealt with..

That link is Ampwares under a different URL. I have ordered from them and eventually got my stuff. I'm just afraid what would happen if I had to straighten out up screwed up order. I actually see they have them at Newark and I was planning on getting some CD PVC caps from them anyway. Thanks for the Express boards BTW.
