It's a hybrid, possibly a 12B13C52 chassis. 1971 I think, with ultramatic tuner.

That is a nice looking Zenith!
I believe I've offered before to look up the service info for you if you can give me the chassis number.

If you don't know the chassis number, then remove the back cover and there should be a chassis number printed on a sticker on the HV cage right in plain sight, if that sticker is gone then look for one pasted to the inside of one of the sides of the cabinet.

I tend to agree with you Jon as to the most likely chassis to be in it. I have a 12B13C52 chassis set, and from literature I've seen that chassis was offered with the same control layout as marco has.

The chassis number is always the best identifier of a Zenith set IMHO since the service data is cataloged to make that the easiest number to look up, and the fact that Zenith usually offered the same chassis in various cabinets with a different model number on each cabinet.

Thank you for your nice comments.. Here is the chassis number that I saw on the label on the left side from the cabinet.

serial number : 5400070

TV chassis: 25CC55

The other numbers are illisible..


The pictures showed are from the owner before me...now my tv is in my basement but i made some efforts hey!!..lollll removing stock on it, back and in front of the tv.. well, I have lot of stock

First year solid state "flat chassis". Uses pass regulator
instead of the regulating transformer.
The flat chassis sets are considered by most including me
to be the best color TV's built by anyone, anytime, anywhere
You have a gem.

Zenith CM-120 service data has your set. I have the training module from 1971.

CM-series manuals show up on ebay all the time. I don't have one, nor do I see one eBay right now.

Cheers,

It's paper, and my only one. 87 pages, not an easy scan. Lots of good info, I'll see what I can do.

Cheers,

I don't know what you mean by " FLAT CHASSIS " My TV uses a metal chassis..

[rca2000]

Flat chassis refers to the way it is laid out...on a relatively FLAT metal frame. built MUCH like a tube set--but solid state. The 3 model years of flat SS chassis (along with the 4 tube hybrid sets from the same time frame, also a flat chassis construction) happen to be what many of us consider THE BEST tv sets EVER made--bar NONE.

As for the safety caps---they are on the flyback board. If white they WILL need replaced. If they look like an " orange tubular blob", known as [orange drop" they are likely OK.

If they are white you must change them. If they are
orange they are OK to use.

I guess those C-line flat chassis don't give as much of a grace period for CRT survival, if any, when a white safety cap opens.

okay. From what I know and see. I have no tubes ( glass ) on the chassis..I have already had in the past with tubes and it was a portable RCA but I was fool rid myself 5 years ago ....

If I understand, I have a quality Tv isn't it?
