Hi all,

My amp has developed an issue were it looses its left channel, I can temporary resolve this by turning the volume knob up and down quickly but few moments later it comes back. Not to sure where to start troubleshooting.

Update: when producing loud sound with bass it will crackle and pop also I noticed if the amp is on and producing sound for a long period of time it will resolve loosing the left channel but the crackle and pop at high volume remains. I am using high quality nordmende drivers from the 70s the right has no issue and sounds fantastic.

Thanks

Do the Source Direct or Loudness functions have any effect ?
