Hello, I got a good deal on an SA750+some speakers and it's pretty good but it has some panning issues I'd like to fix.

The issues that I have are:

-Moving volume knob pans the audio(especially if I lower it all the way) to the right.

-Sometimes audio panning drifts by itself and I have to press the already selected selector switch to rebalance it.

-Moving balance sometimes crackles the sound.

Has anyone had similar issues or has experience with similar amps?
I'm looking for any help I can get, google has been very limited.

I'm perfectly fine with doing anything necessary myself but I need some guidance on this...

Thanks in advance! :)
