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?

Try contacting Audio Research directly.
Their info can be found under the Manufactures database here on Audiogon
Sorry, I was under the impression that AR is not the same company that it was in 1979, but now that I read their "About" page, I see I was wrong. Thanks, it being a long weekend I was hoping to get a jump on a lead, I'll call them on Monday, much appreciated!
