Repairing Home Amp


Recommended Posts

I have a Parasound HCA-1000 Stereo amplifier. I don't know if one of the kids fried it or what, but the right channel is toast. I replaced two of the internal fuses but they blew once I turned it on so there must be a short in the path somewhere.
Any suggestions? Anyone?
I don't see any burned traces, but I haven't completely disassemblied the pcb from the chassis yet.

You are lucky that it has 2 channels and 1 that still works.
Remove the fuses and power and measure for a much lower resistance on the bad channel, probably at the output transistors or power ICs. By comparing measurements of the good channel to the bad one, then you'll find the problem.
