The ground steaks didn't look bad, but I reflowed them anyway. I replaced the 6GY6's, 6GU7's, and 6GH8's, the 6EW8*, and the 6JE6 horizontal output.

*I had to substitute a 6GM6 for the 6EW6, the substitution book says it's fine, and it works.

Are you sure the contacts in the crt plug aren't just loosening up when it gets warm?

The pin(s) on the CRT for the filament were not making good contact with the wires inside.

Speaking of which, it just broke again.

Reflowing CRT pins is not difficult but I hope you're not trying do it with a low-wattage pencil type iron. Use a Weller 100 watt gun. The tips tend to get concave on both sides of the original chisel-point and this is perfect for maximizing contact area. Place your tip as close to the base as possible and feed solder into the hole. It should flow toward the heat spot and full up the pin.

I successfully replaced a broken-apart CRT base on my test jig CRT and its working just fine. I am also working on a CTC15 chassis, that needs lots of solder-pencil work as standard procedure. It also has a shorted flyback (not burned up), for which I have a NOS RCA#113382 replacement that was made in Mexico.
