The PCB's were crappy, etch lifted too easy when repairing them.
Known for bad vert outs & an easily repaired ground loop causing
hum bars. The last US Zenith B&W's were on 9" & 12" sets apx 1980.
They were modular but they left out the "service saver" chassis.
Great running sets but a real PIA to service. It was modular but the modules were to expensive, component level too much trouble.

I've had a few of the 19" and one 22" "tin can" with the upright modular chassis that was a pain to service. The horizontal solid state modular chassis that was made prior to this one was easier to service. When I was in high school, I recall seeing a 19" that looked like the one that the OP has, but it used a hybrid chassis.
