70.161.216.205
...When I went to the electronic scrap junk warehouse sale today. I went in, and sitting toward the front of the place was a Pioneer SX-1980! I snag it and a few other goodies for $20!
Cosmetically it needs some TLC. The Plexiglases on the face is broken, the bass control shaft is missing, and a few knobs are missing. Electrically, it seems to be all there. It does power up, but the speaker relay does not click in. Doing some troubleshooting, I believe the power transistors, 6 per side, may be OK. If I unplug the harnesses going the the output transistors, the relay does not click in, yet if I unplug the entire driver board, the relay does kick in. I am suspecting the DC offset must be out of whack.
Any ideas here?
The tuner appears to be functional. :-)
I want to get this bad boy up and running. This will be a great receiver to use in my main set up. Problem is, I need to build some speakers that can take the 270 watt output!
Anyone know what the sound quality is on one of these?
Mike
