Title: Amertran catalogs ? Post by: Opcom on April 28, 2017, 12:34:10 AM Amertran catalogs seem rare. Anyone know where there are some scanned ones? AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
I found one - Bulletin 1002B April 1939. I am looking specifically for data on those narrow range autotransformers as used to set filament voltage within a narrow range. Usually it is like a slider-type or linear 'variac' driven by a worm shaft giving only few turns of the hand-sized knob, and an output of 95-125 VAC. The pic is a 0.25KVA one in the Tucker KW. I found a 1.1KVA one in the stack here and want to know more about them. |
