- Notes
- Philco 48-1000-5;
10" round CRT b/w TV with 12 channel US FCC standard VHF turret tuner, 50 Hz mains power supply model!
The Philco model 48-1000 television was introduced in 1947. It has an 8-channel turret tuner with plug-in coils, so that any 8 of the available channels 1-13 could be selected. A unique design feature is a dual 300 ohm antenna input, intended for separate antennas for the VHF low and VHF high bands.
Three chassis codes were used in the following chronological order: code 121, code 125, and code 122. Codes 121 and 125 are similar, both having 26 tubes. In code 122, the 1N34 crystal diode DC restorer was replaced with a 6AT6 tube, bringing the tube count to 27.
Philco had other TV models with similar chassis. Model 48-1050 was a console version of the 48-1000, with the same three available chassis codes. Model 48-1001 is another table model electrically identical to 48-1000 code 122, but has a simpler cabinet style. Models 48-1000-5, 48-1050-5, and 48-1001-5 have power supplies designed for 50 Hz AC supply, but are otherwise identical to the models without the -5 suffix. Model 48-2500 is a large console projection set with a chassis based on the 48-1000 design, but with several significant changes to support the projection CRT system.
