Have you called ARC? Some years ago they had a manual for one of their old tube crossovers I had and didn't even charge anything to send a photocopy. Good luck and listening!

Audio Research D-52B Manual?
I am fairly new to high end audio and am used to fixing other types of electronic equipment. I have an Audio Research D-52B amp that does not power on and have not had any luck searching ebay or Google to find a source for a schematic/manual/repair manual, I even checked Sams Photofact to no avail, is there somewhere out there I can get my hands on one of these?
