Potentiometer issues

[Sach77]

Hello all

I had a stuck pot that was causing a lot of crackle, particularly in the right channel. I swapped this out and the left channel is fixed but the right still has a bit of crackle. Have I purchased a dodgy pot or could there be a problem elsewhere, maybe with grounding?

Is there DC on the wiper? That is often a cause of crackle.
Maybe show a schematic?

Hi Jan

I assumed that if there was a problem with the wiper, the crackling would be present on both channels..?

How can I check for DC at the wiper?

Thanks
