Not so fast!
First off, I got a new tripod and better lighting on my workbench
Next, I wasn't really happy with having the electrolytics scattered around the chassis. So I found an old cap of the proper size, restuffed it and restored the original wiring.
I also added another 10 ohms to the filament dropped to compensate with the higher line voltages encountered today.
I also rebuilt the old dual diode assembly with modern diodes.
Then the "fun" process of installing the chassis. Remember I was just sent the chassis. The cabinet and CRT are from my set.
It played fine for a few minutes then the horizontal collapsed to a vertical line then disappeared altogether
The sound is still good though.
I pulled the chassis back out and wiggled some wires. That seemed to fixed the problem at first, but after about 30 seconds it collapsed again. I pulled the chassis twice more with the same result.
So it seems to be an issue with a loose yoke connection or possibly over heating. I'm not so sure about heat though because once the problem occurs, letting the set cool down does not help.
