  • Notes
  • DuMont "Inputuner" 101 (102);
    Optional offered combined continous tuning TV-VHF & FM tuner as well as standard used in a couple of the DuMont "Teleset" families and others.
    For manual or motor drive, have a continuous tuning Mallory-Ware Inductuner using a triple roller inductor which covers the VHF low, FM, and VHF high bands in one band from 44-216 MHz.
    72 ohms unbalanced low input impedance, three tunable circuits, two of them for bandpass and one for the oscillator.
    Offered as drift-free. Sold in two versions - motor driven with tubes and dial (Type 102) and manual tuning only (Type 101).
    Compare this concept with the more common type of turret TV tuner.
