If you were a small broadcast station 80 years ago, you might be interested in knowing that you could purchase a Western Electric 451A-1 transmitter for immediate delivery. This ad appeared in the December 15, 1945, issue of Broadcasting. In addition to the broadcast band, it covered up as far as 2750 kHz, and ran from a single-phase 200-240 volt power supply, 50 or 60 Hz.
