This GE audio console came with our DuMont Telecruiser. It is early 1960's vintage and one of the first consoles to use linear (rather than rotary) faders. The strange thing is rather than using a conventional fader like we do today, these faders were actually a ladder of resistors which controlled the brightness of a small light bulb. This light bulb was mounted into a small cardboard tube with a photocell at the other end. The photocell actually regulated the volume as the lamp got brighter or dimmer. There was a very noticeable time lag when you brought up a fader, before the audio gain would change. This made precise gain riding very difficult.
A pair of RCA RT-21 tape decks. One of the record amps can be seen to the left below. Operators loved these decks because they had a "Jog-Shuttle" knob. It makes cuing tapes a lot easier. That idea was quite ahead of its time.
