Fender Stage 160

I haven't turned this one on yet (making a light bulb current limiter first), but I took a glance to see if the outputs were shorted, and immediately noticed one of the filter caps had arced.
The filter cap had a terrible solder joint.

I can see the whitish scorch marks from it arcing. It's C64, and arced to the trace that leads to the rectifier diodes (stripe side of d54 and d55).

The TIP142s are measuring .92m from base to either side.

TIP147s are measuring .94m from base to either side.

Does that sound about right for those?

What is ".92m"?

Check those TIPs from E-C. ANy shorted?

Are you sure the arcing was not just broken solder connection that sparked hard when the two parts touched now and then? Something a simple re-solder might fix?

I should have written 920k, instead. No IC's shorted. I went ahead and turned the amp on and it works. There is a little bit of background hum, but I'm not sure how much is normal for this model. Perhaps that filter cap isn't doing it's job 100% now.

Is that amp one of the sloping bottom chassis types? Rear panel is a lot taller than the front control panel. And are the two main filter caps sticking up from the midle of the board? Resolder both caps, even if it looks like they don;t need it.

[AtomicMassUnit]

Yes, it's one of those.
