I need some help with this one, schematic or stories or whatever, to aid in possible restoration to working condition. This is a theater amp from the 30's or 40's (guessing). The nameplate says it was designed by Electrical Research Products, Inc, subsidiary of Western Electric, for Motiograph, Inc. Tube complement is 2x 300B's, 3x 310B, 1x 274A, and a 42. It is very heavy. The transformers (3) have no markings that I can find, but are large (ranging from 3.5 to 4.5 inches on a side) and probably account for most of the weight. Any info appreciated.
I found a photo of one (not mine, but looks like it) at http://dojima.com/manhattan/audio2.html BTW is this the best place to look for info on an oldie like this? Any other suggestions for forums where I might get help? Thanks,
John
