Havent bought any volume Pots in a while, I used to buy Noble pots for most projects, but apparently they have stopped making them. The more expensive TKD seems to have suffered the same fate. I have located a few 100K Noble units, but need a 50K unit for the BA-3 as pre amp.

For the B-1 I used the recommended PEC pots, but wanted something a little more elegant for the BA-3 as Pre amp I am finishing up. The Goldpoint that 6L6 used in his build was nice, but a little rich....may have to save for it as I am not finding much else out there.

What are the Pass builders out there using for your volume pots? Any help in this regard would be appreciated.

either that , or 10K audio taper from radio mix deck

if not these , cheap Lorlin lookalike switch based attenuator with smd resistors is best bang for the buck - fleabay is full with those

AVC looks sweet, even more $ than Goldpoint! Looks like no cheap way to do this elegant, I'll search Ebay for value dreck...can always replace later with more elegance ($)...

Thanks,

If you are going to build your own, be sure you get a schematic of the pin in and outs by the manufacturer.

Bought one from partsconnexion.com and one miss wire ruined 6 hours of work. Yes, I did test for in and out connections. On this build, the pins were off-set and the first position was actually physically the second position. What a mess! It made no sense. To boot, the switch had two sets of inputs.

Goldpoint has surface mount switches.

Iam using on of these in my ba3, unbalanced. Its worked for 3 or 4 years, had it in multiple preamps, only cleaned it once. Its big though if size is an issue.

I see its a four pole. I see your pre was unbalanced did you just ignore the other 2 channels, and leave them unconnected? Otherwise, how did you wire it to your 2 channel pre? Thanks guys,

(maybe I'm confused, I am assuming "4 Poles" means four channels? If its only 2 then that clears things up...)

No one mentions MUSE...as in XP 30 ?


'course as ZM says ...not best bang for the buck....maybe ...if you take into account the price of matching a bunch of Dales or other to make your own.

But...mainly because not easy to get.

😕
