After asking and reading about pots problem, I have tried everything (even bought that lub) so I decided to open the amp... now It seems like the pot is loose.. the thing helding the pot seems loose.. it just pushes in.. and everything seems loose but doesn't seems to be that way with the other pots... any help with that ? I could post pictures if needed... ! Even the part of the pot where the nut is supposed to be seems loose !

Please :help: :crying:

Well since a week or so the "gain" knob was making a weird sound whenever I was turning it. I've read and asked and been told that the pot was dirty... So I bought the Tuner Cleaner and sprayed some on the knob. Still did not work. The pot seemed loose so I tried to screw the nut tighter.. accidently I took it out.. and now the part where you screw the nut seems loose too. So I opened it and well, the steel plate for the tube is in the way, but the back of the pot, whatever is supposed to held it seems a bit loose compared to the others.. Now the nut won't really go back in since the other part is also moving and well the pot / knob won't move correctly.. budges..

Hi.

+10 for the pics.

Pots are seldom repaired as there's a slim chance that it works afterwards for any longer period of time. I've repaired some on the spot, where the tabs that hold the can (the back part) came loose. That was out of the necessity as some equipment was damaged by rough handling and the two options were no-show or a quick repair.

Some high end sliders and pots can be disassembled and repaired, but unless it's a really special and/or hard to get part I'd replace it with a new one.

Better yet, get it replaced by a good tech.

You mentioned tubes. You do know how to bleed the caps, how to work safely, etc.
Applies obviously to SS as well as tube amps.

Regards
Sam

You don't spray the knob you spray inside the pot itself. What is the amp and where is Hearst?? Questions questions
