  • The Fairbanks Morse 7117 is an AC operated, 7 tube BC, Police and SW band receiver. "Radio Retailing" calls it "F-M Model 7117". Uses chassis 71.  Has AGC, RF stage and 2 stage audio circuit. Was available with 3 different power transformers.

    NOTE: 71 is the chassis number and NOT the model number.

    The following models use the same chassis:

    NOTE: On page 110 in "Cathedral & Tombstone Radios", this model is listed as model 71, which is an incomplete model number.  The picture shown is actually model 7117.
