TV Zenith Solid-state 70's

[Marco-nix]

Hello to all..Anyone has a schematic or/a catalog for this Tv ? any help would be appreciated. I put 2 pictures. Thank you.

TV model or chassis number would help!

[Jon A.]

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,

I have a paper copy of the factory schematic, but not the full service manual (which would include more than the schematic). I'll either scan it or take hi resolution pictures of it for you when I get the chance.

[Jon A.]

Interesting, I never knew any 1972 sets looked like that.

Okay but the schematic will help me for the caps, resistors , diode etc etc... this set works but not completely. The CRT is good and give a nice picture ...The shassis is metal , no tubes on it completely transitorized...

Like cars model year is not build year. The new TV models
started in the fall like cars. So a 1972 built in '71.
Sometimes there are early releases of top of line models.
Usually they are regional. They will have the older year
model number.

BTW there is one thing that needs to be checked before you
run this much, when you dig in let us know.

It's so close to being the ultimate flatty in my opinion. I never knew they were made with ultramatic tuners. If only the styling were anything but French Provincial. My Space Command 500 console is probably the closest I can get to that in a 1973 model.

Actually THREE things::
1--safety caps.
2 focus divider/bleeder
3-Tripler.
