One owner roundies are still out there....scored a Zenith

[old_coot88]

The very first thing i would do upon acquiring a Zenith roundie is check the condition of the plastic (nylon?) H.efficiency coil form. Especially on a high-hours set. If that form lets go, everything else is moot till the coil's replaced.
The three adjustment coils on the convergence panel use the same kind of forms. The middle one looks like it has already let go (of course that doesn't render the set unusable.)

Just the end is broken, the coil itself is intact. That I can fix if needed be. I've had those suckers come apart and unwind.

Picture tube is good, so that's a plus

I'm glad you mentioned that horiz efficiency coil, as I forgot about that one until I talked to a friend on the phone last night about the set, then forgot again this morning! Looks like it's been replaced. I seem to remember those coils having a baby blue coil form, this one is bright lime green, which I can't remember ever seeing. In either event, it looks good.

There's bumblebees and white time bombs under there, so if I check tubes and get a reasonable response on power up, it'll get a recap.
