  • The General Electric model Colorama E-115 is listed at Rider's GE 8-56 through 8-60. The E-115 features the Colorama tuning indicator (see post 5 etc.). The AGC line controls the saturation of the "magnetic amplifier", a saturable core reactor. The reactor is in series with a red stained pilot lamp and a green stained light bulb behind the scale which turn the light to green when a carrior (station) is tuned in. Other Colorama systems have 7 lamps. Weak stations will produce a small color change and strong stations larger changes - a smooth process. This was a novelty in 1936 for GE sets - the Magic Eye was just on the market but GE wanted first to have it's own gadget which was a problem to service men and the cost was over twice that of the tuning eye.

    The model E-115 can have a 25 cycle transformer. Band B (Broadcast) covers 540 - 1660 kc, the band C (Fishery, Police etc.) 1600 - 6000 kc, and band D (SW) 5.4 - 18 mc.
