    Fender G DEC Jr Transformer

    I have a G DEC Jr in the shop with a shorted transformer. It's markings are:
    P/B
    G-DEC JR
    J1-120
    PA 101379 Can anybody tell me where I can get one of these and/or a schematic. What is the difference between a Jr and a plain G DEC?

    These amps are swap-only from Fender. Replacement parts are unavailable.

    Here is the schematics and stuff. Looks like a 30VCT for the power amp with an extra 8VAC or so to feed the 5V regulator and some other things

    From Fender's website:
    The G-DEC Junior is a simplified, super-cute version of our award-winning original G-DEC. This 15-watt baby has an 8 speaker and simple interface with knobs for selecting various amp types, effects types, backing tracks and performance loops in styles such as rock, blues, metal, jazz, country, Latin, hip-hop and others.

    I know this thread is old but... I had a similar problem with a GDEC today. It wasnt the trans. On the pcb , right next to the 2 brown wires , is a small , green FUSE. Looks like a little green resistor , but its a 1/2 amp fuse. I replaced it and my amp works ! Hope this helps

    Did you check the current there? You can disconnect one of those spade lugs to check the current. The .5A is under spec'd. Many of these amps got junked (do not repair list) because that fuse blew. The one I have runs right at about .5A with 124V AC line voltage. So I put a .75A pico fuse in there. If you notice on the schematic it actually shows F2 as 1A on the drawing and also on the component layout.
