If your red led comes on after about 30 seconds you're good. Just open the top and re-solder wire(s) to the mute switch (mine is a Revelation II with balance control, but there's a pic of yours on Audiogon that looks to have the same setup.) If the led doesn't light there's probably something more complex going on with you system.
Repair a Superphon Dual Mono Pre-Amp
I'm looking for someone that is familiar with the SUPERPHON REVELATION dual mono PRE-AMP that is technically skilled and can implement a repair. The pre-amp is in perfect functional condition so far as I know with one exception. The "MUTE" function does not work. Unfortunately, the failed default condition is "off" and not "on" so this difficulty is causing the pre-amp to be non-functional. I have been trying to get a line on STAN WARREN, the designer, with no luck. Even someone who has a schematic for sale would be helpful. This is a great pre-amp that I would like to be able to use again.
