Wow! What a schematic! Did you know that in 1937 WLW, at least, was hi fi? Maybe other clear channel stations also had permission for 10 kHz audio bandwidth. WLW ran 500,000 Watts and used a 250,000 Watt high-level modulator that was flat from 60 Hz to 10 kHz. In those days music was live and sounded WONDERFUL. Playing of commercially-pressed records was illegal.
