1977 Zenith Chromacolor II 25HC45
There's an old house that hasn't been lived in for ages, and the lady never threw anything away. As you can imagine, the house is in bad shape, stinks to high heaven, and there's cigarette glaze on everything. One of the family members is having a sale there, and I've gotten a total of 6 TVs out of the house. The three I left behind (I'll probably end up with them, eventually) are an early '80s 19" RCA XL100 with a single-knob tuner, and a busted off tuner shaft, and two early '90s 19" RCA XL100 sets (CTC146).
This one here is a 25" Zenith Chromacolor II that was made late-'76 for the '77 model year, and uses a 25HC45 chassis. This set smells about like what the entire house smelled like, the power cord is missing, and the only thing holding the back on is the twist tabs. I'm sure it's fixable, but cleaning it up and getting the odor out of it will be the biggest chore.

I tested the jug and it took the blue a little while to come up, but it eventually woke up (the set probably has not been turned on in 30+ years). As far as delta-gun tubes from that era, Zenith tubes held up the best.

To make a long story short: the CRT was testing at %10-15 on my B&K 466 where most other color tubes that touch the bottom of the good range (which is %50) look worse and dimmer. To put it further into perspective the scale on the B&K is calibrated for color tubes where %85 of the guns output is blocked by the shadow mask... Monochrome tubes that don't have that limitation will typically act like a weak color tube when they get below %30....That Chromacolor tube was putting out a good picture at half to 1/3 of what an aluminized monochrome tube needs to look OK. Unbelievable! Zenith Chromacolor CRTs are good to the last drop.

Interesting thing is D - E ( & maybe C ) line SS flat chassii and
E & maybe F line CC2 AND 12, 16" Zenith Taiwan B&W hybrids were instant on. IMHO it shows instant on is not a bad thing when used on a SS set. It should NEVER be used on an all tube PCB built set, especially with compactrons ! I would always defeat it on those sets. Its as easy as snipping one end of a diode in most sets. We used to do it for a few bucks when a set came in if the customer wanted. Turned out to be an obscene profit center ! 73 Zeno LFOD ! |
