I was just given an old Pioneer SX-3700 receiver. It needed a bit of cleaning up but otherwise everything works. I do find it runs a bit hot and would like to verify the idle bias. There are not alot of pots on this thing. The only 2 sets I can see, one set looks like a power meter adjustment and the other 2 are in the tuner section. I don't think it would be wise to start adjusting any of them just to see what they do. A schematic would be nice but if someone can jut tell me which pots or even their general location, I can figure the rest out.
