9.89v on pin 11 of the power supply board. I also get that same reading across the zener diode that is @ D206 right before pin 11 near the card on main board and same voltage on pin 2-1 of the audio driver card. There is no voltage on any other pad of the audio card (still removed).
On the power supply driver card I have: Pin 1: 12.79v Pin 2: 4.34v Pin 3: 12.79v Pin 4: 12.14v Pin 5: 0.000v Pin 6: 12.78v pin 7: 0.176v Pin 8: 0.000v Pin 9: 0.000v Pin 10: 3.08 Pin 11: 9.9v Thanks for your help on this one Perry... Its driving me nuts, lol. There is no real visible signs of damaged components anywhere. I've been over this amp several times. |

Are you sure that the trace that connects pin 11 and pin 2-1 doesn't split off anywhere?
Can you post a photo showing the entire board?
