I have just started to restore a Pioneer QX-8000 quadraphonic receiver and started out by trying the different modes. It quickly became apparent that when in stereo mode that there was hardly any sound from the left channel. After trying a few other settings I then switches the receiver off and rather than the sound dying away it came on properly on the left channel as well as the right for a few seconds!
I'm suspecting that there must be a faulty capacitor somewhere - am I right in this diagnosis> I have checked the 4 2200uF caps on the output of the 4 amplifier sections and they all test a little higher than spec with low esr.
Any suggestions on where to start looking next?
