  • Notes

  • Magnavox model 264K is a blond wooden console combo with doors, incorporating an AM/FM radio, phonograph, and 16 inch TV. The audio amplifier is a high-end design for its day, with push-pull 6L6G output and a 15-inch coaxial speaker with a 4-inch tweeter using a capacitive crossover. The phonograph is an early 3-speed changer, with an unusual cartridge (not turnover type) that rocks between two positions to select between two styli on the bottom of the cartridge -- a "standard" stylus for 78 RPM records, and "LP" for 33 and 45 RPM records. The stylus is selected by a lever near the pivot of the tonearm which controls the tilt of the cartridge. The TV has a 12 channel standard US VHF tuner and uses a voltage doubler to generate a 14 kV high voltage supply for the 16EP4 metal CRT. Some units use a 16AP4 metal CRT, as documented in Sams and the tube placement chart in the set, which indicates only one 6BG6G horizontal output tube in that case. The video detector is a 1N34A germanium diode.

    The date range was estimated by manufacturing date (29 December 1949) stamped on the chassis and the date on an original sales document (24 December 1950). The diode 1N34A was probably on the market in 1950 but was designed in 1949.
