THE-NIG Posted January 2, 2023 Share Posted January 2, 2023 Hello there ! I have a question to put regarding Ampeg BA210 . The volume knob has a mind of it's own , it crackles , farts even when the volume is at zero . Does anyone know or have had experience of this themselves and what is the best way to rectify this niggling problem . Cheers !

BassmanPaul Posted January 2, 2023 Share Posted January 2, 2023 Getting the pot replaced is the best option. Spraying copious amounts of contact cleaner into the pot is not a permanent fix and can damage the part even more. Quote Link to comment Share on other sites More sharing options...
Bigguy2017 Posted January 3, 2023 Share Posted January 3, 2023 Does tapping the knob produce the crackle? Could be the pot itself or it could be a dry solder joint. Give the pot a squirt of Deoxit and a few twists. Resolder the pot's connections on the PCB. Tap around the PCB with a plastic pen or similar, to identify dry solder joints - reflow any suspects... Replace the pot. Quote Link to comment Share on other sites More sharing options...
BassmanPaul Posted January 3, 2023 Share Posted January 3, 2023 (edited) Sorry @Bigguy2017 Dioxit is more likely to wreck the pot. Edited January 3, 2023 by BassmanPaul Quote Link to comment Share on other sites More sharing options...

I've fixed so many dirty pots with Deoxit and it is actually formulated for this purpose. Also if the pot's f!*ked anyway what have you got to lose? It's easier than replacing the pot, which may finally be necessary. Over 45 years as a Broadcast Engineer I have never had Deoxit harm a pot - cleaned literally thousands of carbon track pots this way - entire mixing desks. Don't believe ignorant chat on the internet... https://caig.com/cleaning-and-maintaining-pro-audio-gear-deoxit/ Edited January 3, 2023 by Bigguy2017 1 Quote Link to comment Share on other sites More sharing options...

BassmanPaul Posted January 3, 2023 Share Posted January 3, 2023 @Bigguy2017 Just as a question, what was the need for the foul language or is it just the way you speak to others? 🤯 Quote Link to comment Share on other sites More sharing options...
