Here's mine of the same model. I found this at the side of the road when I happened to glance up a side street on my way to a bowling league. It was in pretty rough shape with bad cataracts. It had most of its original tubes (and several very weak ones), but the CRT was in excellent condition.
The first time I plugged it in, it had no vertical deflection (bad connection to vertical tube heater) and the degaussing VDR started smoking because the thermistor was bad. I used a wire brish wheel to remove the rust and repaint the back, bottom, HV cage and IF cage. The chassis cleaned up ok. I scanned and reprinted the warning label on the HV cage after cleaning it up in paint shop. The only real electronic problem it had was failure of the degaussing thermistor/VDR pair and a few high ESR caps. It's now the TV I used every day in the work shop and hasn't given me any trouble in the year or so that I've been using it.
I'd love to get a new control door for it because the original was rusty and there's no way I can think of to reproduce the wood grain and the Zenith logo.
