I know I have spare rectifier tubes, just need to find which box I put them in...

Anyone have the schematics for this?

I never worry, when I see a cracked tube, I just try another one.
The CRT might come back. It was probably dormant for 40 years.
I like that chassis a little better, as it uses a 5U4 instead of a voltage doubler, like the next years models. I always admired the horizontal hold control design. One of the early multi-turn types.
The set you have, has the metal back. The next years models had a back that was made of some funky, crumbly plastic that didn't stand the test of time.
