parts sourcing question

[AndyMack]

Fired up my Sylvania roundie not too long ago, and just as it came up to full raster, the entire HV section went out. No nothing on the right side of the set, and the CRT is dead too. Anyway, I was in the process of pulling the H.O. tube when I found that i couldn't remove the top cap connector. After a few minutes of trying to finess it, the whole cap broke off of the tube. Well, my luck I suppose. Turns out it was a 6LR6 in place of the 6JS6 that's supposed to be there. I had an NOS 6JS6 on hand, and installed it. While trying to pry out the old pin remains from the cap, the cap then decided to shatter. Perhaps I'm just a butterfingers when it comes to this stuff or maybe it's an omen to try to dissuade me from repairing this TV. Typical of the luck I've had with this old set.

I'd really like to have this set up and running to record the analog shutdown of our local WRGB (oldest TV station in the nation) in February and need to source a new grid cap for the 6JS6. Anybody know who sells these things? I have nada in my limited parts stash.
