i would guess a cap blew, and overheated the power transformer, should cost about $150 to fix, and the speaker is worth maybe $2-300, depending on the model

You should be able to read the value of the capacitor on the side

I know this is an old post. I put this here for others with the same issue as I have worked on these before. Call Samson and ask for the schematics - they will email them to you if you ask nicely.

As for issues I have seen with these:

The protect relay on many of these is notoriously cheap (Alesis used the same brand and also had difficulties). This is worth checking straight away if your power supply seems good. It is a DPDT12v on the control side and rated at 5 amps (the relay will say 10, but it's 5 amps on each pole).

I also had an issue with the PCB being bent within the enclosure as it fits very tightly in a plastic shroud, and then into the wooden enclosure. This caused some of the solder joints to come loose on two of the power transistors. So, if you see that the PCB is bent a bit, check all those solder joints.

Hope this helps someone.

When any electrical item doesn't work after being moved, suspect some kind of physical cause. Such as a bad soldering joint or other damage inside caused by an unknown bang or jolt during the move. Perhaps even an alien object inside like a metal pin etc.
