Or find a local audio technician.

well you were not clear on the power protection relay at all
and if tripped can never be ignored.

you meant i bet, power protection relay (fires off and activated)
that means these things, (the schematics are clear)
1:speakers shorted,or there wires, test with none !
2: output drivers Audio power amps are shorted, 1 or more.
this is seen as and ******* DC offset voltage to speakers and can wreck the speakers so it trips, saving lost of $$$$ speackers
this is how they all work AVR too .
to find it takes hard work on a beach, with the schematic
and testing each output driver for faults.
the manual shows the tests and good readings, at the driver.
some can trip for over voltage and overcurrent at the power amps.
moved you out of cars and trucks it is no CAR.

Did you check whether the protection assy is working properly? The protection circuit is checking the current of the power transistors as far as I remeber. So there are several possibilities for that fault.
You should grab the service manual or at least schematic (http://elektrotanya.com/pioneer_sx-850_sch.pdf/download.html) and then go step-by-step. I recommend to start up with the protection assy itself. If this works properly go for the power amp. It is also not unlikely that the power supply is the cause of the problem.
Good luck.

Using a higher voltage fuse is not a problem, but if the fuse you used amps are to high, that is a problem. Sounds like a resister burnt. You have a short somewhere in that particular circuit, which is what took out your original fuse. . .your fuse did it's job by blowing and saving the circuit. If you can get your hands on a schematic, you can trace the circuit and find the short.

You can get full schematic about your device using this link:

Good luck, good work!
Thanks.

Yes, you can use them but be careful. These are not necessarily robust speakers. If they sound strained, back off.

The Pioneer SX-205 does not have remote control capabilities.

You appear to be pretty savy but your best bet is to get a hold of a schematic so you can really trouble shoot. Did you try a google search? Check with vintage gear sites? Pioneer?
