Folks, I have a pair of interesting UTC transformers that I need information for. Any experts out there? I cannot find a listing in any of the easily found UTC literature, but I have likely only scratched the surface. Maybe they were special order or military? The only markings are on the side: UTC W-1090, then a second line 706-105. They are round, 2 3/16 inch diameter, 2 7/8 inch tall, with 16 terminals on the bottom. Resistance measurements show 4 windings, none identical. Weight is about 19 oz. They are similar in style to the RC-50 case shown in a 1953 catalog, but they are larger. Any information would be appreciated. Incidentally, there is a non-USA e-bay listing for an amplifier that shows up when googling this. This listing indicates use for a SE OPT of 15K ohms to voice coil. If true, this could be a fun transformer for a low power SET. I would really like to see a catalog listing or data sheet if anyone can help. Thanks, John |
