The stereo part was a AC/DC, AM radio with a simple S/E 50C5 output stage. The phono was a simple manual 4 Speed record player, using a turntable and a tone arm, as found in a school type phono. It had two 5" speakers, one for each channel. The TV used it's own output stage, with those speakers.
The color TV was the common CTC15 design, that everyone seemed to use.
The CRT was a left-over Zenith OEM 21FBP22.

I don't quite understand the radio/stereo portion, specifically I'm curious about the filament string. I picture an ordinary AA5 chassis, but that would be mono, obviously. If there were two 50C5s, was there a selenium rectifier?
