Mystery set at a sale this weekend
Might go get this, depending on what it is. Any guesses? Almost everything after ~1974 I won't bother with at this point. It was a very dark picture - I tried to enhance it a little.

At first glance it may be a Zenith CC2 with 18 pos
selector. Sure its mid 70's to early 80's. May be something rare like Philco or Admiral SS set so worth a look-see. 73 Zeno LFOD ! |

I agree with Zeno, go take a look at it, looks like a Zenith CCII to me, as well, I'm thinking mid to late 70's vintage, as best as I can tell by the picture. Good luck!

I'll definitely take a look at it. Maybe if it's free, or in mint condition I'll get it. If it's a remote set, consider it already in my collection. Here is the original picture.

Yah, that does make them more interesting. I have three types of ultrasonic remote sets: one with a 20-position motorized varactor tuner and a side-scrolling channel display, one with a motorized VHF tuner (didn't know that is a remote set until it was brought to me) and of course my fully-electronic Heathkit GR-2000. Of course I didn't get the original remote so I'm using a newer-style Magnavox Star System remote for now.

1976 Zenith System 3. Got it for The Best Price. When I showed interest in it, they pretty much begged me to take it.

I'm thinking the manufacture date label is worn, I don't think the System 3s were out until 1978.

TOTL consoles. As far as I know System 3 was never used on the sets or in literature. K line brought the name & ad campaign. Sets were 19" & 25". System 3 was a feature list not a chassis. J & K sets used the 9-153 HV module not the 9-160. They were the most reliable sets Zenith ever built. Also the CRT's used a green phosphor that was stunning. One thing I never tried that I would like to is swap the 9-152 with a 9-152-02 that has a comb filter. L line brought the 9-160, comb filter, 13" & 17" and RAT tuner. Reliability dropped but sales went through the roof...... 73 Zeno LFOD ! |

This is a very interesting observation.
I believe by this time they had dropped the cadmium from the green (which made it brighter, but yellower, producing a cyan color bar that was very grayish). (The cadmium was determined to be an environmental hazard.) This means that the green formula was based on copper-activated zinc sulfide like everyone else's green, but there could be unique differences among makers depending on the use of co-activators like gold or aluminum. With the deletion of cadmium, the efficacy of the green was reduced such that it could be the limiting primary for tube brightness rather than red, for D65 color temperature. However, no TV manufacturers at the time setup for D65; they were generally much more blue/cyan, partly as a habit from earlier days. Zenith used a unique 8000K setup that was not as blue as others, but still had a clean white look that accented reds and yellows by contrast, and provided more stable skin tones. I don't know exactly what combination of activators Zenith used in green or the exact color coordinates of the resulting green. I also note that the "stunning" nature of a particular color bar can be influenced greatly by the color demodulator gains and angles. |

Displays a decent picture. CRT is pretty tired. Takes its time warming up.

It's a 1976. Clear as day.
EDIT - set was made June 1978. I misread the label three times in a row. Only got 4 hours of sleep last night.

Don't tell me CRT's don't wake up! After using this thing for a while, the CRT has woken up big time. When I first got it, I had to have the brightness cranked up to get a usable picture. Today, I put the NTSC generator on it, and if I didn't know any better I'd say somebody rejuvenized when I wasn't looking.

CRTs sure do wake up, but they can die of shock too...I had a LONG dormant 50's monochrome rebuild yesterday come on testing almost full scale then slowly sag with small jumps downward till it was near completely dead....Would not take a rejuve either.

Probably would be a good idea to bring it up real slow on a CRT tester in a situation like that.
