Postwar American Television
(1950 - 7 inch)
Sprayberry Academy of Radio, of Chicago, provided this kit to its students in its radio and television training course. The set was assembled in stages, with temporary wiring, so that students could perform experiments. In the earlier stages, the chassis is wired as an oscilloscope, so that the waveforms from the sweep oscillators, audio section, and video sections could be displayed. In the final stages, the chassis was wired as a TV receiver. A 7JP4 CRT was used.
Our kit was shipped in 1954, and is incomplete. We have the front panel, the chassis, and the parts and instructions for lessons 4, 5, 7 and 8.
