Hi guys I have the crack with the speedball upgrade. Everything was going fine until a couple of weeks ago the amp started to get noisy eg hum poping cracking noises. Makes noises now when there's power and Headfones connected by itself. Any tips on what to check?

Both channels or just one?

Does the amp ever cease to operate all together or is there just some intermittent crackling?

Does the crackling have a time consistency?  By that I mean, does it happen after the amp has warmed up for a while, or just all the time?

was both channels, thanks for help guys, was a weird problem noisy as hell even more when you turn the volume knob, but noise wnet away when you tilted the amp to the side. Noticed the b section board screw was not tight so re tightened it and bent acouple of pins on the volume knob underneath and pure silence now.

Cheers guys
