Thanks Allen. I didn't see your post at first. I'm on it. Tom

Thanks Bobby. I think this was Maggies last mono before they went to stereo. The transformer in the pic is an output transformer. There is no step down power transformer, just a rectifier tube. Legs are heavy duty on this unit.

I picked this sweet little blonde up at a yard sale this past weekend. I need the schematics for the amp. Radiomusem.org has an AMP-167AA listed but no 166. Any help would be greatly appreciated. I believe this is a 1958 model.
