  • Annotazioni

  • The Fairbanks Morse 4015 is an AC operated, 4 tube BC band receiver. Has a regenerative second detector in place of the usual IF amplifier.  A small variable coupling capacitor between the plate and the grid coil determines the amount of regeneration. Alignment procedure located in Riders Volume 7, page 7-2.

    Band Frequency Ranges are as follows:
    BC Band......................540 - 1720kHz

    NOTE: 40 is the chassis number and NOT the model number.

    The following models use the 40 chassis and schematic:

    Other Notes:

    "Radio Retailing" November 1935 - new models - means that at least early October the sets were ready. The majority must have been sold for Christmas. The following upright table models were offered as new: 4015, 5619, 6616, F-M 7117, 9018, 4115, 6416 and "down-to-the-floor construction" consoles 5645, 6645, 7146, 9047 and 9048 plus the battery model 6445B. The first digit tells the number of tubes. Plus models 11049 and F-M 11050 with 11 tubes. Fairbanks-Morse called its new loudspeaker and AF technique "third dimension tone".
