Pioneer SX-737 issues

[Ed in Tx]

DC on the outputs detected by the protection circuit doing its job preventing DC to the speaker connectors. Probably fried a final or more and\or drivers, maybe a diode or more. Resistors need checking too. No telling with no checking for shorted transistors etc., but that's where you need to start.

So basically you're saying that I fried the output transistors and some other components in that path when I accidentally installed the replacement differential transistors in the wrong way.

If that's the case then I may just have to junk this receiver out then because there's no way I'm going to find some replacement output transistors for this receiver because they're the old socketed Germanium output transistors which are no longer made and they don't have any modern replacement's for them either.
