I thought I'd share this schematic (didn't find it on here when I searched).
Several years ago, I bought a couple of broken Fender GDEC Junior amps on ebay, and fixed some. Attached is the schematic that I got from Fender (great folks to work with).
I still have one that is in my 2-year-or-so queue for repair (was repaired and working, then I went to put it in a cab with speaker, it failed, so it went on the shelf).
Phil in beautiful Talking Rock, Georgia, USA.
Thanks for posting that.
Early on they had too small of a fuse in the F2 spot for the 5V supply. It's the soldered in picofuse. They had a T500mA in there and then they changed to a T1A. It runs right around 500mA and would sometimes blow from turn on surge or high line voltage. I fixed a couple using T750mA and never had a problem after. That was before they updated to T1A, which is probably and easier value to find.
No idea if that is a problem with yours, just thought I'd mention it here.
Thanks :) :dbtu:
