As you may have seen in the June finds and losses thread, I just got this cute little cathedral radio. It seems to be quite old, maybe late 1920s or early 1930s. It has a two wire, twisted, cloth covered power cord. The tuning scale is the old 0-100 type, not the later frequency type, which makes me think it is an early set. There are no IF transformers, just two coils mounted on the top of the chassis. I am thinking it is a TRF set with one stage of tuned amplification before the detector stage. I haven't traced out the schematic yet. It looks to be a job and a half if it comes to that. Here are pictures of the set including the chassis from front, back, and underneath. The tube line up is two type 57s, the control grids of which have leads that go to the coils, a type 47 audio amplifier, and a type 80 rectifier. Here are pictures of the set and of the chassis. There are the remains of a paper label on the back of the chassis, but there are no other markings on the set which would tell me the maker. If anybody can tell me who made it , and hopefully the year so I can look for it in my Rider's, I would appreciate it. If you either have the schematic, or know the volume in Rider's and can tell me that too, that would be even better. Any help is appreciated at this point.
