I made this find recently and was thrilled to try and muscle it into the Jeep and finally home without too much damage. I shared this on antiqueradios.com; and all of my queries to my usual radio librians and researchers regarding documentation have come up empty. A tag inside the transmitter has a note about the set with a date of 1939. Mostly Taylor tubes, a final amplifer T-55, and modulators #756. 866s for rectifiers. There are three shelves: PS, modulator, oscillator & final amp. The most curious things are the aluminum plug-in units labeled A, B, C, D, one set for each band. I have complete sets for 20, 160 meters, and will be on the unobtanium hunt for the missing ones. I know I've seen these units once before... It was stored recently in a damp environment and there is some chassis and cabinet rust, so I'll have my work cut out for me. I broke a 756 tube in the move and luckily a friend had a replacement. RME corp., Serial number is 80, and it looks like the model number is 175RT. Owned originally by W3IBI, a doctor in Vineland, NJ. Just wanted to share this, and as always, comments are welcome. .
