Zenith 16D25 Parts

[sambo521]

Hey Guys,
It's been a really long time since I've been on here.
It's been almost 40 years since I worked on Televisions for a living and I have recently decided to start restoring some old sets.
Anyway, My first victim is a Zenith B/W set Chassis # 16D25.
I managed to get the set to come back to life but a few issues.
First off, I checked the CRT with my Sencore CR-70 and it was very strong.
However, the yoke plastic has completely disintegrated, electrically it seems to be okay. Don't have a photofact (466-2) yet so don't have a part number.
Thinking about making a plastic mount.
Second the filter choke is completely shot and needs replacing.
And finally, the flyback in this set looks horrible but it works and may replace it if i can find one.
My thing is I have no idea where to get parts for these old sets anymore.
So I guess the question is, where's a good place to get old parts and also looking for line cords for these rigs.
I enjoyed working on this set and its got a long way to go but it does work so that's a good thing.
Thanks for the great group.
