    They used this chassis for various models and the cheaper ones have the tuning selector on the face of the dial. This one was designed not to have that dial-string tuner pot on the bottom. This should be a TRF- typ "curtain burner" radio, which had a resistive cord that gets hot and would light your curtains/house on fire. Remember that when replacing the power cord you will probably have to tack in a resistor as well. One of the caps looks to be replaced likely in the 50's, and the getters in the tubes looked fairly good, but with the getter migrating to the bottom they will be gassy. Also to note the TRF style radios were considered local-only types, so don't be surprised if it isn't a DX champ. Never seen a TRF with shortwave though. If you can fire it up make sure you find (or build) a longwire antenna. An old trick was to wrap wire around your copper water lines under a sink for ground antenna. I made a fair one coiling wire around a thick cardboard tube.

      You can probably get some comparable schematics on radio museum online. With a set that simple find one that uses the same tubes and they should be nearly identical. 11:57 you would be surprised. If the voice coil doesn't rub (can also be fixed), you can bridge the holes with paper and a little glue. I believe I heard Elmers is good because with that glue dries it allows some movement isn't too brittle. Those speakers with the audio transformer permanently mounted are hard to find and a pain to replace. You can even get a little paint and hide the patch.

    Very nice video. I am currently working on a similar type of set with the name plate of General manufactured at Plant A. Like your set mine also has a second band on the dial face as well as AM. I am no expert, but from what I had found some radios were manufactured both with and without the K55B tube. The schematics on the radio museum site had a notation that if the K55B tube was in the circuit it did not use the resistive line cord (curtain burner). Just something to look in to from my research.

      Thanks for the info! I plan to do a follow-up video where I delve into it in more detail and maybe even try to get it going. Might be a while before I get to it, though. :-)

    I would be very happy to have that radio and restore it
