Hartke B600 full of pops and cracks

[Davidof]

Hey

My Hartke Bass amp makes a lot of unwanted noise, especially when turning the volume or waveform knobs.

It's constantly jumping to random volumes, also when the knob is at 0, I have some elektronic experience, but can someone tell me where to start looking please?

Thanks
David

Clean all the controls and jacks with professional grade cleaners.

Beyond that look for any sign of mechanical sensitivity or loose connections.

After that we approach any electronic noise.
