Check D3. The small glass diode connected to pin 7. I feel as though it is shorted. Give me the reading across that diode!The reading is 1.76
.583
Well D5 is the STV-4H biasing diode. If it is reading .533, then it is bad. Are you sure about that? What about D9??D1 .572
D5 .533
D7 .528
d5 seems low compare to d6
d6 is the other channel and good comparison .
just measure the known good one first .

yes it was academic . but things like this might be the cause of the problem . no harm in checking .

Check the foil side (back) of the Amp board for shorts between the foils. And check every resistor in the circuit. You can make comparisons on the right channel. Also check all the caps too.D6 is 1.211
