Troubleshooting a Fender Champion 600

[Danielboom]

Any techs out there good at diagnosing? I'm not doing too well right now so taking it to a shop is not an option, my only working amp is a Roland Micro Cube. I need my tube back.

Last time I used it I unplugged the speaker to test out another cab, I then forgot to reconnect the speaker wire and turned it back on. It then smoked a little, and there's some sute on the board. I've been told before it's probably just a short from turning it on while it was unplugged and the speaker wires had no where to go.

Everyone I've talked to this far thinks it's just a resistor that needs replacing, if so. How do I determine that? I feel confident finding one online (resistor) and replacing it, but not much beyond that. As my abilities/knowledge don't go much farther then basic soldering.

Any feedback would be appreciated.

Thanks in advance.

You could easily have a fried output transformer and/or other burned up components in the power section of the amp. What you describe is probably one of the worst things you can do to a tube amp. Your amp has a speaker jack that shorts to ground when nothing is connected...that is good, but it sounds like it didn't save your amp. Sorry.
