Thanks for responding. I have the users manual with the block diagram. I found a local guitar amp repair shop that could repair it if I had the full schematic. I've also made contact with Dave Slagle of hifiheroin who has been rumored to perform mods on the PH-1. Maybe he'll be able to provide some help. I've also tried to contact Sean Ta who owned AYDN and Artemis Labs but I've had no success so far. I'll keep you posted as this progresses.
where to get schematic for Artemis Lab PH-1
My Artemis Labs PH-1 has developed a hum in the right channel and I want to have it repaired. It appears that both Artemis Labs and Aydn (distributor) are no longer in business. I have it mated to the Artemis Labs LA-1 line amp and I wish to keep the pair in my system. To me they provide vinyl magic. I have a VPI Classic II with a Benz Micro Ruby 2 HO MC cartridge. I'm willing to send it off for repair if I can find a facility that will do it. Would even consider a mod if that's what it takes to get it repaired.
