• Remarques

• The General Electric E-101 is an AC operated 10 tube BC, Police and SW band receiver. Has dual speed tuning controls, with fast tuning ratio 8:1 and vernier tuning ratio 40:1. 

  The General Electric models E-101, E-105 and E-106 share the same schematic (Rider's GE 7-29 through 7-32 and GE Service manual 1935-1939 pages 213 to 224) 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 to first have it's own gadget which was a problem to service men and the cost was over twice that of the tuning eye.
  
  The 6J7 is for the AFC - not used in models E-91 and E-95. The band B (Broadcast) covers 540 - 1680 kc, the band C (Fishery, Police etc.) 1680 - 6000 kc and band D (SW) 6 - 18 mc.

  The E-101 was available with 3 different power transformers:

  Rating Label	Input Voltage (Volts)	Frequency (Cycles)
  A	105-120	50-60
  C	105-120	25-60
  V (Universal transformer)	Taps at 115, 125, 220, 240	40-60

  Note: Stein "Cathedral & Tombstone Radios" lists 4 bands for this model (model actually has 3 bands).
