So I've had some time to pick at this. I bought this set 2 days before I was supposed to leave on a 2 week vacation so the variac job was stolen time.
Since getting back I confirmed that the H Lin coil is intact and the slug moves freely.
Also looking closer at the chassis I've found some interesting things. Someone wired the outlet half of an extension cord into the chassis (I presume to make the remote control something else).
The convergence yoke has one of the bridges between the clover petals cracked and a metal band wrapped around the whole clover. I've never seen one of these clovers intact and installed so I don't know if this is factory or an aftermarket repair.
Some of the work on the TV was done by the type of neanderthals who remove half the screws on a cover then bend it open like a can of sardines.
The good part is it appears the stereo hasn't been worked on. Every unshielded tube is original Zenith with 48-51 week of 1962 date codes. All the audio tubes worth anything are good. The 6FQ7s aren't super strong but the rest are including the made in Holland 6BQ5s (which I believe are rebadged Philips).
Thanks to Dave I have the info on the KV-24 reverb I now know what reverb it should have had. While on vacation I was excited because I remembered I had a chassis that I got years ago with some FM MPX decoders that wasn't one, and a spring unit. I couldn't find the spring unit and the reverb driver chassis I have is I believe for an older Zenith...the circuit looks the same but it has its own power supply (which the one for the Chancellor lacks) and different plugs.
