| Check the fit of the left channel connectors with your cable
connectors. Make sure the signal and ground contacts are tight and
dirt free. Connectors actually change size as they warm up - so any gap
may disappear after the equipment warms.
Beware also of cracks in your cables that create intermittent breaks or
low quality connections that may change as the cable heats up.

If the Carver has relays on the outputs then one of them could be
getting crappy.

| Since it didn't do it at the shop but does at your home it leads me to
believe that it has something to do with your home environment. If the
cable connections are OK (verify by swapping L/R) try hooking up your
amp far from any other equipment and check the grounding of the ac
power. It might be an obscure RFI or ground loop problem.

| An obscure RFI or ground loop problem that disappears after 60 seconds
suggests a thermal component to the problem or an oscillation that
requires 60 seconds to die down.
Or a timer circuit on the relay output is partially opening the relay
and degrading the signal.
Is the delay always 60 seconds? Even when the equipment is hot?

| No, the delay is only when it's turned on COLD. As for the problem not
showing up in the store ... well, that's what the tech said ... not
believing him, *I* tried it in the store (amid screaming guitars/keys/
drums/people/etc) and really thought that I, too, heard NO problem in
either channel at the store.
Looks like I'll have to do some more experimenting at home ... then
maybe taking it back into the shop (store) ...
Other than a 60-second inconvenience, this isn't really a problem for
me - once the amp "warms up" it works fine thru the whole gig. But,
I have to wonder if this is a harbinger of further problems down the
line ...

| Buy a can of the spray coolant for electronic troubleshooting
(try Radio Shack or U-DO-IT Electronics type places) and see
if you can recreate the problem. Maybe it is only a thermal problem.
If you cannot recreate it by chilling the components, the circuit
board, or the connectors, then you have a real headache.
