  • Modello: TV-101 [Early] - Mallory, P.R. & Co.;
  • Forma
  • Soprammobile compatto/con bordi arrotondati/midget senza pulsantiera/tastiera.<= 35 cm (Sometimes with handle but for mains only).
  • Annotazioni
  • 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.
