RCA 14-S-7070G Horizontal Shrink After Recap

[fsjonsey]

Thanks for the tips everyone. I swapped the HOT with a NOS Russian 6p31s I had lying around from a amplifier project, and it definitely has improved the horizontal problem. It still shrinks over time, but not nearly as bad as it did.
Phil, I've been visiting your website since I was a kid in the late 90s. I've loved this set since I first saw it on there years ago, and it was a contributing factor to grabbing this one when a customer brought it into the cigar shop looking to sell it last week. We're in an old house located next to an antique store that's also in an old house and people often mistakenly come in with stuff to sell. This time I lucked out. I got the TV for $25 and the lady ended up buying a few cigars for her husband too!

Well, late 1990s (1997, to be precise) is when I bought my first 14-S. It took me several years of off-and-on puttering to finish that one, but the second one went faster. Here's the new article, for what it's worth:

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

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.

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.
