[QUOTE="fdlsys, post: 778150, member: 2310"] Bawb, I think the lack of response is not due to seriousness of the ground loop issue (assuming that is the problem of course), but due to the fact that it is more often than not a beech to pinpoint, especially when it comes to complex factory built amps. This requires hands-on, pictures will seldom help. As far as one channel running warmer - it's typically a biasing issue. But, depending on how the biasing is done on that amp, it could be a circuit or a simple fixed value resistor or a trimmer pot. Schematic is a must, and usually best left to professionals. [/QUOTE]
