  • Notes

  • Mallory model TV-101 early is an AC operated all channel UHF convertor.
    With germanium or silicon point contact diode as UHF mixer. This converter has classic styling and it was one of the very first UHF converters. It was a very popular model. Converts US-UHF Channals 14-83 into US-VHF Channel 5 or 6, uses the Mallory Inductuner, OEM Production with Type/Brands: Arvin 3000, Alliance AC-80, Sylvania C33M, CBS-Columbia, Silvertone 6950 (Sears, Roebuck & Co.), Sparton, Mall-Ex, Crosley DU-UHFP, Sutco 23A.

    Later that same year, a 2-tube chassis version Mallory TV-101 [Late] was manufactured. The later circuit also uses the 6AF4 oscillator and 1N72 or 1N82 mixer, followed by a 6CB6 IF amp, with a selenium rectifier stack (instead of the 6X4) for high voltage.

    Note that the 3-tube Early version has a S/N less than 200,000; the 2-tube Late version has a S/N 200,000 and above.
