What do fuses do in an amp?

I carelessly hooked up my combo amp (Fender Bassman 25) to my SWR 4x12. No problems there. The ohms match up and I didn't even crank it that loud.

 

But then I wanted it louder. So I routed my last cable to the PA rather than the amp. But then I wanted it louder (I was playing drums to a loop) so I connected the 4x12 to the PA. Or so I thought. I actually plugged the PA speaker (from it's I/O) to the external speaker on the practice amp. Whoops.

 

When I smelled old burning amp, I didn't know what it was. Then I opened up the amp. The fuse was fried but so was the surrounding area around the heat sink where it connects to the main board. D'oh!

 

Do fuses only do so much?

Yeah, fuses only do so much. You put the practice amp in parallel with the PA cab.
:D

Sounds like you might have fried the output transistors.

 

I was just so damn excited to play with my new Boss Loop Station that I lost a chromosome or something.

After reading your first post again, you hooked the the PA cab to the speaker out of the practice amp? While the practice amp was plugged into the 4X12 and the PA cab?

 

:eek:

 

It's no wonder it fried.

After reading it, it doesn't make sense at all. Let me try again.

 

I ran my bass into the PA. I connected one speaker of the PA to the external speaker jack (8 ohm max) of my 25 watt practice amp. I was supposed to add the 4x12 to the PA. D'oh. :facepalm:

Still doesn't make sense. How were the PA and the practice amp connected?
