  • Bemerkung
  • The General Electric models E-101, E-105 and E-106 share the same schematic (Rider's GE 7-29 through 7-32) and feature the Colorama tuning indicator (see post 5 etc.). The triode 6C5 commands depending on the AGC line the saturation of the "magnetic amplifier", a saturable core reactor. The reactor is in series with a row of 4 red stained pilot lamps and 3 green stained light bulbs behind the scale which turn the light to green when a carrior (station) is tuned in. Weak stations will produce a small color change and strong stations larger changes - a smooth process. This was then a novelty 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 teh tuning eye.

    The 6J7 is for the AFC - not applied for the models E-91 and E-95. All these models can have a 25 cycle (C) or 60 cycle mains transformer which came in two versions, one fix for 105-120 volts (A), the other for 105 to 250 volts with 4 tappings (V). The band B (Broadcast) covers 540 - 1680 kc, the band C (Fishery, Police etc.) 1680 - 6000 kc and band D (SW) 6 - 18 mc.
