Samson MDR8 blowing internal power supply fuses.
Here is a troubleshooting hint:
Put an incandescent lamp in series with the hot side of the power cord. This acts as a resetable fuse while troubleshooting so you don't blow fuses.
Schematics are hard to come by, but power supplies are easy to trace the circuitry.
Check filter caps and the diodes and THEN look for hot (temp) IC's and transistors.

The most likely case is that one of the main output transistors (if which there are many) is shorted. When the protect circuit senses DC on the final output, it will not allow the output relay to come on to protect the speakers from raw DC. With the power removed, you can check between each outputs Emitter and Collector and you will probably find close to zero ohms. From that point you need to unsolder each of the pins of the bad channel until you find the shorted device(s) and replace them.
