Hi Bob, I also have one of those receivers and found your message while googling for a manual. On mine, the power supply also was dead. At first, I found a shorted electrolytic on the power supply board. Replacint that got some positive results but there is still a problem and I suspect some more power supply issues. There is a resistor ( R556) near the two N-chan mosfets that has overheated and I can not read the value. Can you tell me the value of that resistor if yours is ok?
