Default Photos won't load

I've spent the last 3 hours trying to post photos of the P45s board to this thread- and even though they are sized properly- it's a no go. The pictures are in my "gallery" in diyaudio, however so...

Here's a link to the photo of the board in my gallery:

Sigh. Ok then, here's a macro shot of the side with burns...

It appears that you allowed an unfused remote wire contact one of the speaker wires. What color wire connected to that terminal of the plug?

One last macro of the burned side. Used 2 desk lamps and no flash to try and get light while eliminating glare.

No, the transistors weren't clamped- just the aluminum plates were in place behind them. The whole thing took about 3 seconds to go from crackling static like before, to smoke and burns on the traces...

I'm sure you're both right (and a genius.) The old electrical tape I had wrapped around the remote turn on lead had fallen off- and while the speaker wire connections were covered, they were not covered real well- because the tape is losing adhesion. So it is entirely possible it made contact with either the black or orange wire... (forehead slap)

Look at the pin that's connected to the burned trace. Does that go to the black or the orange wire?

So, in your opinion, what sort of prognosis do you think this amp has?

Looks like the burned area on the left side goes to the black wire.

That's not one of the active speaker wires so the output transistors may have survived. You may not need to do anything other than repair that trace (if it's actually burned open) to get back to where you were.

Please read the basic repair page (link in sig line below), paying special attention to the information in the yellow box.
