Is the combo the one you are calling the coffin?

Ya mind if I ask where you dug it up?

"The box above the HV cage is the remote chassis"
Remote chassis for what?
Phil

Take a wild guess, there's a radio and a TV in it...

Never seen a Space Command chassis in a black cage before and got confused.

I'm smart enough to know what it controls.

Yes, long combo is often called a coffin model.

Aerials, who has been much more than kind and generous, found it and eventually gave it to me based on the expectation that I will restore it, as I did the family CTC-5 that he gave me a few years ago.

d'oh (slaps forehead) -- I did the imitation of a pretzel required to focus my bifocals on the inside of the cabinet, and found the info last night (will post when I get home tonight). I'm going to try snapping a pic of the labels so I don't have to do the human origami trick again.

I think one chassis was a K and the other a L, will post the full numbers.

Here's the coffin diagram, 25LC30. The console is 25KC20U.

took the back off the stereo side - it is "11L8T25Z chassis", stamped in ink

Possible year of Zenith close?
 

I am thinking 1962 or 1963? Im sure Wayne you will get facts on this monster set. I am still trying to get that ctc-5 up in Auburn, In. I will try to drive up this weekend and beg as best I can. he has vintage B/W sets from the 1950's I have no desire for. You Guy's spoiled me with Color round tube sets. I look everyday to find and rescue another roundie. I thank everyone of you talented technicians to breathing life into historical sets.

Even though your set has chassis 25LC30 it sure looks different from mine. Check out the differences with the convergence assy and the power transformer! What date codes do you see? Mine is a very early 64 before the UHF mandate and no space command.

I've seen the finned power transformers before, never paid attention to what sets they were in. Regarding the convergence coils, is it possible yours were replaced at some time? (I'm guessing mine weren't, since there seems to be the same layer of dust on the tube neck as on everything.)

The 25LC30 is covered in sams 722-4 and my convergence assy looks like the one they show on the rear view pix. Variations are always possible....

Remote chassis
 

Silly me. When I saw "remote chassis" my mind switched to "remote (tuner) chassis", but I knew that wasn't right. About as bad as when I read "General Cement" and my mind switched to "General Concrete". Miniman82, I'd really rather have a Wild Turkey right now than a wild guess.

WOrks for me, take a shot and down some A&W. Sounds odd, but the caramel aftertaste mixed with the Turnkey is glorious.

Put a DTV converter box or cable box on that set and you won't need Space Command, as these boxes come with their own remotes that will operate the set's basic functions -- including on-off in most cases (see my note below). The Zenith DTT-900 and DT-901 are two very good DTV converters from what I've read here (never had any experience with one because my flat-panel set already has an ATSC tuner and remote, though I am presently using a GE universal remote with the TV, my VCR and DVD). Unfortunately, however, the on-off button on the DTT-900/901 boxes won't work if your TV doesn't have remote control, but the other basic functions (channel +/-, volume +/- and probably mute) should work just fine. VK member Electroking in Montreal has one of these boxes on one of his older TVs without remote; the power button on the DTT-900/901 remote won't work on that set either. In these cases, you must switch the TV on and off manually, or else get a switch on a long cord that plugs in between the AC outlet and the TV. I don't know if this type of "wired remote" is still available (I had one back in the '70s), but if you can find one, it will more than compensate for the lack of on/off switching at the converter box remote, although you will need to be wary of the cord. Zenith's first TV remote control system, the "Lazy Bones", was introduced in 1950 and had the control unit on the end of a very long cord; that cord was unsightly and also created a tripping hazard, as it often ran across the room in which the television was located. The Lazy Bones system was replaced with the Flash-Matic remote, Zenith's first wireless TV remote control, in 1955; the Flash-Matic, after only one year (!) and many customer complaints, was replaced by the Space Command ultrasonic remote system . . . and the rest, as they say, is history.
