Hi. I have a Fender Princeton Chorus amp that's around 15 years old. For a
while now I'll be playing and the amp will fade out for a few seconds then
come back to normal. I've tried several different guitars and cords, and
am plugged directly into the amp.
Would there be a fuse going out or something in the wiring?
Thanks!

It could be alot of things really and is hard to get down to the problem
when we can't hear or see the amp.
I would check the speaker wires, try turning all the effects off and see if
it still fades. A volume pot could be dirty and needs to be cleaned
etc.......
Normally it's something simple especially with a solid state amp. ____________________

Good deal, I'll inspect and clean it throughly to see if that helps.
Thanks for the help.

I would say the volume pot(s) too as I had the same problem before on one
of my marshalls.

Don't overlook any bad connections including but not limited to
broken/cold/oxidized solder joints and/or defective component on the
circuit board. Leakylytic caps are another source of trouble as well as
dirty/defective pots as others had mentioned. Any of these things can be
the source of your intermittant problem and the resultant grief
experienced. Minimize the variables by process of elimination; first
eliminate any devices in your chain (pedals etc), then substitute your
guitar & patch cord for known good units to eliminate them as a source of
trouble, wiggle your patch cord at your guitar & amp to see if the problem
comes & goes or no difference. You may have already tried this, never
overlook the obvious & ALWAYS UNPLUG YOUR AMP BEFORE INSPECTING OR
SERVICING! Good luck, Keep on Rockin'.
