In Reply to: one of the least talked about amps? Electronic Industries (pre-ARC) M60 ? posted by m8o on March 20, 2007 at 13:30:51:
The amps in question were marketed by Fulton and also sold in very limited quantities by ARC as the M-60. There is even a rack mound faceplate (I have a pair of the amps, which I purchased years ago with the faceplate)that allows a pair of the amps to be bolted for rack mounting. I also have schematics and the circuit is very straightforward. Floating paraphrase inverter for the first stage with a cross-coupler leading to the differential driver. Screens of the outputs are regulated. Updated with modern parts and these are SWEET amps.Regarding the later posts referring to the Paoli 60Ms, Walter Key did some of the original design work with Gene Coggins, but there was an instability problem. Dave Conklin, who died several years ago, perfected the design and made them reliable. Jeff Medwin has some excellent mods for the 60Ms and I own a pair of these as well.
