Zworykin CRT Receiver

1928 Prototype with Vladimir Zworykin, and Laboratory version of the same prototype. This was unusual it that it used magnetic deflection for the horizontal sweep, and electrostatic deflection for the vertical. It is thought that the set operated with only 48 lines, and 20 frames per second. Though we have this set under RCA, it was actually developed by Zworykin while he was still with Westinghouse.
