The large hump is there, as well as the speaker jacks. The data plate I've seen in other Apex 36 photos isn't. Would it work with a self-energized electrodynamic speaker? Any idea what that AC socket is for? Also, do you have any suggestions on freeing up the rusted gear mechanism in the tuning system? I don't want to mess up the varicap.

Ooh, I didn't think of a self-energized electrodynamic...I suppose if the impedance is in the ball-park you'd be good to go. Perhaps, as you theorized earlier, that is what the AC Socket was added for.
By the way, it's cool that yours has all "S" envelope tubes. Mine had a full set of Philco "S" envelope tubes (with paper stickers) except for the 227 detector. I found an RCA globe 227 in my stash of tubes so it would have a complete lineup. Mine had already been restored by the previous owner (RIP, it was from an estate sale), but I pulled all the tubes out for cleaning and testing, before reading about Neutrodyne sets and that the tubes were "neutralized" for their particular sockets. I need to re-neutralize it now, as it howls terribly at one end of the dial. I've made a neutralizing tube-socket adapter, just need to sit in front of it and do some methodical twiddling. As for the rusted tuner, I would just be dribbling a couple drops of Liquid Wrench on the shaft where it goes through the frame, probably several times over the course of several days. Let it soak in. Be patient and gentle, I think it should be able to be freed up with penetrating oil and care. At least we are not dealing with pot-metal! Oh, and mine has a sheet-metal panel for a shield between the rectifier and the rest of the tubes. I'm still looking on various computers for those pictures I took... One thing I notice about yours that is different is that it has frequency markings on the dial. Mine just has the typical 1 - 100 logging numbers. That has to be an early implementation of that type of nomenclature...I wonder if it was a retrofit? Any way, have fun, this particular type of radio was only around on the market for a couple of years, things were changing so fast. --Bob Last edited by Bob E.; 04-26-2010 at 12:11 AM.
