Hi,
This is my first post, on behalf of my teenage Son. School show tonight & he has taken his amp into school.
Unknown to him 'Sir' has plugged his speaker out into a line out to a mixing desk.
Unsurprisingly he ended up with smoke, and now no power!
What can be done please folks. My lad is gutted.

I would bring the amp to a repair tech and charge the teacher.

A little unclear whether you know specifically who plugged it in. And no mention of whether the person who did it admits doing it and acknowledges responsibility (and/or if there are witnesses).

Have you checked the amp's fuse/fuses? There's at least a chance that's all the amp needs.

Hopefully just the fuse, but they dont make smoke when they go. :(

Hopefully, whoever misused it will pay f9r the repair. It might be cheaper to buy a 2nd hand one than getting it fixed though, simply because of labour time.

I cannot raise a schem to the Crush 60 but I am surprised that as an SS amp it died with a load mismatch.

I agree I would check that a fuse has not popped as I would always expect that first even feeding the speaker into a very high load (unlike a tube amp).

If that does not work then worth a basic check with a tech first before exploring liablity issues!

I'm afraid that's a little more than a load mismatch, which happens when the incorrect speaker impedance is used e.g using a 4 ohm load in a 16 ohm speaker load, that's a load mismatch.....the thing that's happened here is the output signal from the amp looking for a load has come into contact with the mixing desk also looking for a load...something has had to give and it sounds like the amp unfortunately. What was the mixing desk and its power rating?
