Vibration-proof bias pots?

....................

Oh, here is the schematic I got with the amp LOL.

Ick!

I think that "schematic" crashed my computer.

just an aside, but if the question is "vibration-proof bias pots?" isnt the answer multi turn pots.

something like this?

I would totally use something like that, but currently the pots are panel mount. I guess the only benefit to the panel mount is tht you can rebias without opening the back of the amp (there are banana jacks to measure current across 1 ohm resistors), but I really don't care that much about that. I could probably mount a small pcb without too much surgery.

What size pots and resistance? I have panel mount locking pots.

They are 1/4" shaft 50k linear. I may hit you up if my other options don't pan out.

Thanks!

Have 10k i know of. Will have to search a few boxes.

rotary encoders shouldn't be vibration sensitive....are there any ceramic capacitors in the signal path that have temperature characteristics of either X7R, Z5U, Y5V, etc
