In search of Pot - Volume Pot that is
Posted on Aug 25, 2008 under Amplifiers & Amps |Being new to blogging, I hope I am not out of line and didn’t get all the hippies riled up with my title, nor do I want to be out of line asking for assistance, but I am in search of a pot for an old 1972 Sunn Studio lead 2-10″ speaker transistor amp.
This baby is a very cool amp, and it’s loud and clean and reminds me of the good old days! But the pot was going bad! I tried a 25k pot and a 18k pot, old stock I had laying around, not very happening if you get my meaning - blah at best actually.
I believe the pot to be a CentraLab Pot 1347230 3/8 shaft - 23-1113, it tested at 15k?
I am not sure this is the right value (going bad and all) The original pot is soldered to pc board with a ground leg acting as support for the pc board. I’ve tried various supply houses, no luck. Any help would be appreciated!
A close match to it was $150.00, not an exact match either (NOS) I only paid $120.00 for the amp at a local pawn shop! Great shopping there!

Hey Buck,
Nice site all about fixing guitars.
You can find out what value your pot is with a volts ohm meter VOM, you should be able to put it on the resistance or ohm setting and measure what you have between contacts. Compare those readings with a pot of a known value and you should have a pretty close answer at least. I’ve also had good success taking potentiometers apart and cleaning the contacts, sometimes the dial gets wore out though and your done.
Good luck tracking down your pot, I hope you don’t have to go all the way to Columbia
