I may not be the best qualified for remote troubleshooting (seen some very
methodical guidance offered on this list many times), but these are my
thoughts:
If the signal chain of the additiona gear you mention doesn't affect the
gain / average power of the signal (adjust if so), then eliminate each piece of
gear individually (take 1 out, put back in chain, take 2 out etc) and check for
improvement.
If level "shouldn't" be a problem (I.e. if amp headroom appears to be
sufficient) and the amp is overloading thermally, I tend to suspect inaudible
(high or low frequency) in your signal. It could be e.g. that one of your
digital (i.e. sampling) effects units is contributing significant out-of-band
power if it lacks sufficient post-filtering. If that is the case, putting it
upstream from anything that does have good HF roll-off should improve the
problem.

Needless to say, this doesn't sound good!

Now I'm in over my head for sure, which was why I called
Furman in
the first place. I may take your comments and run them by the
guy I
talked to, just to see what he says. He was pretty thorough in his
explanation to me previously, but I didn't hit him with the scenarios
you are proposing either.

Call an electrician in other words?
Thanks
