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.
