Sounds a bit like your amps might be going into thermal shutdown. If you're
not overloading it by signal, other potential sources of overload are hum, a DC
offset problem (if DC coupled), or (inaudible) excessive RF interference
coupling into the amp. Neither of these are necessarily solved by a supply
filter such as the Furman. It would take some investigation if it's not simply a
matter of trimming down your average power level.

I
have been following this thread with interest because I'm also
having
power issues--but not quite the same thing as what you're
dealing with,
however.
My amps are cutting in and out on me. The signal starts to
wane and
decay until, eventually, it (or the two amps together) falls
silent.
Then, after a little while, the signal comes back. The whole cycle
repeats itself every so often.
What to do about it? I called the
guys at Furman. The person I spoke
to, Christos (extension 120, if you
call him yourself), was immensely
helpful. In fact, you may want to call
him and describe your problem
in detail. The solution that he
recommended for me (and perhaps the
same would work for you) was to get
the Furman AR-1215 Power
Conditioner/Voltage Regulator. Here's the
description of the unit
from the Sweetwater catalog:
"The 15 amp
AR-1215 AC Line Regulator protects gear from problems
causes by AC line
voltage irregularities. Delivers a stable 120 +/-
VAC for input AC line
voltage between 97V and 141V."
As an added bonus, all Furman products
have built in surge
protection--real protection, unlike strip outlets,
which I've been
using to this point.
So, perhaps you should look
into the AR-1215, or at least give Furman a
call.
