zenith roundie combo in WI

I'd say that's a '64 model since the stereo has tubes. I thank Zenith went solid state with their stereo's in '65 or so.

Thanks! The older the better! I love the tube stereo, It is also wierd how the speakers are hooked right to the tv, bypassing the amp. There is a switch on the power control that connects the speakers to the tv when its on, otherwise the two units are separate entities. I am used to how the Maggies are made, everything works together and cannot be separated. The Maggie stereo gets power from the tv chassis. The Zenith stereo has it's own power cord.

Beautiful set, great find.
Checking the book "Color TV Servicing Made Easy Vol. 2" lists Zenith chassis 25MC33 as a 1965 model. The SAMS Photofact index also shows it as a '65. The set may have come off the line in late'64 as a '65 model. The tubes may also have been manufactured in 1964. What a bear that must have been to move down the stairs. Take care with your back.

Thanks for the info, Steve. I like to find out as much as possible about my sets.
Last night I set the convergence up, it looks pretty good but I think the usual selenium rectifier replacement is nessesary on the convergence chassis but that will be a later project. Picture looks good enough. The only problem I had was what appeared to be a grid to cathode short on the CRT, thank God it wasn't. It turns out the socket is bad and the connections inside are loose, if you wiggle it some of the wires get temporarily interupted causing the picture to go green, flicker colors and have retrace lines. Tapping gently on the neck does nothing, just wiggling those wires makes it happen. I temporarily fixed it with some white plumbers tape {no glue} just around the socket where the wires go in so I could work on it. The thing I really don't like is the fact that some "tech" cut corners by rigging that thing years ago instead of replacing it. The focus lead corroded and overheated melting that part of the socket, that was enough to replace it in my book. This guy soldered the wire directly to the pin on the tube {rolling eyes} I hate those kind of repairs. The guy also left all the wires in the set just hanging around in there ignoring all of the wire ties and holders, very sloppy work! Probably who ever worked on it back in '69, their name isn't on the tag. I wouldn't put my name on that kind of work either. Will update some pics shortly.
