There are a few possibilities: security camera duty (there were tons of security cameras there when I was getting my degree and they may have had use for one or two back then), 'Chicken stick' remote monitoring of dangerous equipment, TV repair course guinea pig (they use to offer degrees in radio and TV repair in the tube era), etc. Only way to know for sure would be to ask a staff member that was around when it was in service.

I've got it working good enough for my taste now. There is some new pincushioning of the horizontal that bugs me a bit, but I'll ignore that for now. It is easy to get drive lines if the width and drive controls are not balanced.



Most of the tubes have 57-22 and 188-4 I'm guessing that means 22nd week of 1957 and 188-4 is probably GE's EIA code. Given the CRT says 57-30 I'd guess this set was made in mid to late 1957. All but 3 tubes in it were original looking GEs tubes...two were Sylvania one was missing.
There is a part of me that finds it ironic that a monitor that has several desirable audio tubes in it (12AX7 12AU7 12AT7) has no audio section. What is weird is that it seems to use a 12AU7 as the vertical output...It strikes me as sending a kid to do a man's job...
