NBC Radio City, San Francisco
Recording Room
Circa 1942

This room in the Radio City building was the center for all program recordings. Six transcription lathes were used to make recordings on 16 inch 33-1/3 R.P.M. vinyl disks, fifteen minutes to a side. The four turntables at the rear of the room were used for playback purposes only, to audition recordings. The rack cabinets contained program amplifiers and audio switching equipment.
