I have a RadioShack amplifier. Every time I switch it on it makes a noise like it's drawing very heavy current. I'd spell the sound it makes but I don't know how to spell BOUFFFF. It used to come on despite the big scary noise. The last time I turned it on it did that in a very strong way and never started up. The fuse is blown. Not just burned out with a ball on either end of the filament, no, the fusible element is completely turned into metal balls. I don't know if the transformer is bad or not. No obvious signs of problems, no burns, no trauma, no physical damage. Transformers are not my forte.
I have the cover off and the drawing depicts the circuit from the plug to the transformer. There are no electronics there except for whatever is under the mystery switch box. It's a circuit board covered with a heat shrinkable tube. I CAN cut it off, but before I start hacking away I'd like to get some information if possible.
I'm imagining there are probably some capacitors in there. I don't know if any of them can be responsible for the fuse blowout or not. And I'm assuming it's a simple locking push button. There can't be much more to it than that.
I probably will cut the shrink tubing off and inspect it, and I will post a diagram of the switch.
Thanks everyone for the help on this.
