I've got an amp here (Quad 303) with some problems. Whatever I do, the left channel is very weak compared to the right channel.
I already tried to exchange all the input and output cables but that doesn't make any difference.
The problem can't be in the pre-amp since it has none, it just end-amp with 1 button: power on/off.
Does anybody know what could be wrong with this amp?
Normally I'd say that some transistors where blown up because of overloading the amp, but since the sound on the left channel is perfect (no weird ticks or whatsoever!) I don't think that's the prob...
