Fender Hot Rod Deluxe - distorted, low volume output

[5thumbs]

Hey Gang,
I had a friend with a Hot Rod Deluxe that was motor boating. It started in the drive channels and then moved into the clean channel. I removed the circuit board and replaced all the filter caps from IC to Ruby Tube equivalents. All of the IC caps had brownish "gunk" coming out around the positive leads on them so I was sure they were bad. Re-installing the circuit board, I flipped the amp on and now I am only getting a low volume distorted output (should have checked it before I put it back together! ha!). Someone had mentioned that the plate resistors could be the cause, but they all seem to check fine with an ohm meter. Does anyone have experience with this happening? When the filter caps blew, do they take other components with them? Power resistors seem to be fine, preamp and power tubes have been changed for known good ones, voltages on tube pins seem to be within the norm, bias seems normal....HELP!

Make sure you are plugged into the correct Speaker output jack.These amps will exhibit the symptoms you described if one plugs into the Ext Speaker jack without first having a load on the Speaker output.

Hi SG,
Thanks for the tip. I assumed I was plugged into the correct jack?? They are not marked and I was using the shunted jack and not the parallel wired single jack. Is that not correct? I won't be able to get back to this until Tuesday.

oking at the rear of the chassis, the correct jack is the one on the left. (closer to the power cord)
