I also have one of these sets, so I'll be watching.
I notice two holes punched in the tuner bezel... Does this have an optional UHF Tuner? If so, I've never seen them arranged side-by-side on a Zenith roundie... Usually it's diagonal.

Worst case resistors were (Sams numbers) 470K ohm R184 was 950K ohm, 470 R82 was 1084, 22 R39 was 36.1, 22M R129, R130, R131 were 30.3M, 30.2M, and 32.5M. The rest were over, at, or just under their tolerance above their design value. I wanted all of the resistors to be within their tolerance, figuring they specified that tolerance for a good reason. I did find one bad factory solder joint on R158 that made it read open when checking between leads of the parts it connected to.
Yes this set has a UHF tuner which mounts to the right of the VHF tuner (when facing the front of the set).
