I am recapping a S24 Scamp module that I recently purchased. Also it has been modified with a 5K gain pot instead of a 22K. Are their replacements for the Sfernice P11 pots ? Been looking but cannot find these. Also replacing the 15V regulators. Should I add thermal paste or pads? There are none to be seen.

Are their replacements for the Sfernice P11 pots ?

sometime ago I bought some pots that look like those ones in Farnell, I think they were Vishay branded. Do a search there.
Anyway if you don’t get the same exact pot just use one that as similar measures and that fits


Should I add thermal paste or pads? There are none to be seen.

I always use thermal paste in Regulators and ICs that get hot

OK. Thanks The pcb is marked 22K Linear so I am guessing that is the correct pot for the input gain. Newark is the USA website for Farnell so will check there. For the regulator, should I also use a pad such as mica or silicon pad?

The mica is just used for electrical insulation if they didn’t need insulation before they will not need it now.
2 different things, Mica is for electrical insulation and thermal paste is to to improve heat dissipation

Got it. This module has about 20 adjustable resistors… once I get the new gain pot installed, I will plug it into the rack, but may need someone to adjust it. Does anyone know if there are instructions from ADR for this unit? I do have lots of sales type brochures on ADR Scamp …but no set up information.
