RA300 dropping 2nd channel

I have an Alesis RA300 amplifier that I've used for the past few years, I bought it new, and I like it alot......recently it's begone dropping the 2nd channel or the "right" channel. This seems to be spontanious and sparatic. There seems to be no specific level or time where it "turns off", and the level indicators confirm lack of signal.

This amp has XLR, RCA, and 1/4" inputs and I currently use the 1/4". I'll try using differnt inputs later tonight when I get home. I've lready removed everything in the chain prior to amplification exept for the original signal source (for obvious reasons).

Has anyone had this happen to their amps??? As always all help is appeciated.

Thanx
 
2014 - The same problem here - anyone with solution, please..? Thanks!

What kind of troubleshooting have you done, if any?
Can you force it to drop the signal by moving the volume pot or any of the input/output leads?

If you swap the left+right in/out leads, does the fault switch sides?
