I'm looking for the service manual for the Counterpoint SA-3000 Preamp. I know the designer used to sell it, but he has since closed up show.

The particular problem I'm having is that the IREF LED, LED503, is not lit, which indicates the high voltage section is not functioning. In addition, the 555 timer that switches the relay is not turning activating. These things worked before a recap, so I suspect I lifted a pad, but I need to know where.
 
Got some stuff but this is all

It's probably the timer circuit. If the timing capacitor is a large value electrolytic,
you may have to use a special low leakage type for the circuit to work properly.
The capacitor leakage "resistance" has to be much larger than the timing resistor feeding it.
