RCA 14-S-7070G Horizontal Shrink After Recap

[fsjonsey]

After replacing the HOT and playing the set for a few hours a day, what was left of the Horizontal shrink problem has seemed to cure itself. Maybe there was a resistor that absorbed moisture or something, and playing the set has dried it out? Now I just need to find a good 14RP4A CRT and make a new Yoke cover. This one is partially disintegrated but still holding together enough to keep the centering rings in place. A friend might be able to 3d print a new one for me. A local shoe repair shop is also going to make a new carrying handle for me for $20.

Living next to an antique store where people wander in wanting to sell old stuff -- that sounds like a dream come true!

Actually, I work at a Cigar Shop that's next to an Antique store. It's almost as good as living next to one, and I get to smoke inside while working.

EDIT:

Also, would there be a way to add some basic form of DC restoration to this set?

Hey, I love problems that cure themselves. Some coils have cardboard or composition forms that may be affected by moisture. On the 7-inch Hallicrafters TVs, some people take out one little coil and bake it in an attempt to make things right.

Re DC restoration, here's an older discussion of how that might be done in general:

Let me know if you try that solution on this TV and it's worthwhile. I agree that this set could benefit from DC restoration.
