Fender GDEC Junior Schematic

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).

  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.
