Hi guys. I know this is an old thread and not only that it's my first post but I just came by a YAMAHA CR-600 myself. The trouble is that it died about 10 minutes after firing it up. I was going to use it as a power amp for my nad pre and I fired it up and got as far as connecting one of the speaker and it sounded good. Played for a few minutes and then suddenly the volume started sinking until it vanished. Now everything lights up as before and the tuner seems to be picking up a signal but I'm getting no sound in any way shape or form.
If anyone has any clues I'd be very appreciative.
Do you hear a relay "click" shortly after power up?
