Worst Cataract - can you top this?
1968 Westinghouse CP88A18A works but needs some love.
My first attempted cataract repair. Unheated storage probably makes it worse. Anybody have one of these animals? |

Neat set! That has to be rare. That should come right off after a nice long soak in the hot summer sun.

I had a console version (same exact chassis) but hastily parted it out after carelessly knocking the CRT socket in my over-crowded shop. I figured a series-filament console was way too cheap and not worth my time. I wish I had my time machine, I'd go back to 1979, cause I have not seen another.
It sure is interesting on the inside with circuits using series-string tubes that only some North Jersey Engineers (probably from Emerson) could come up with. This is no RCA clone. Just like GE, these were sold as a sideline with appliances, not real good sets, but simple to fix. |

I have Seen this Set Before!!!!!
It is Definitly a Genuine set!! I fixed some of those. The biggest Customer is Ponderosa Hotel they have at least 25 of them!!!! It's Chassis Model # is X-2656-xx (Usually the model # ends with any last two numbers. It's chassis was mainly design for use in 23" and 25" models so, that why the cabinet of the 19" set in the picture is so wide! It's HV cage that houses the flyback transformer and the HV Rect shapes like a Apollo Saturn 5 Rocket. Refer to Cataract problems I have understood that is a VERY COMMON PROBLEMS! This kind of problems has nothing to do with CRT emissions. so, once again It's Chassis Model Number is X-2656-XX (end with any last two numbers) |

I sold one of those sets that was labeled "Bradford". Anyone that would own 25 of them must of been a "glutton for punishment". The color circuit was simular to an RCA design. The tubes were the series string counterparts. Curtis Mathes also built a clone of that model.

Just got the sams 920 it on fleebay. It is a V2655-x chassis. The V2656 is the console version (Sams 969) using a 25GP22. That HV cage description is right on. The tubes are very repetive....RCA circuits.. too many 6GH8, 4HZ6. Half of 8FQ7 G-Y amp is a pincushion amp, several transistors make for very interesting circuits and even more interesting.

hey...as someone who thumbs-thru Sams for fun, I have to chime in.: I tend to go for oddball, interesting circuits...This is a prime candidate it seems !

I was given this exact model set in 1977. It had been dropped and had a crack in the circuit board.
I got the board to flex just right, and popped the crack back in place. I jumped every broken trace, and finally, it lit up. I never did get color on it, but it had a terrific B/W picture. I sold it for $60. In the early 1970's, I had another of these sets. Even then, the flyback, which was fried on this example, was unobtainable. I'd say this was around 1972-73. I loved the rocket HV cage, and all those 6GH8's. |

Another great find! That is about the most gruesome cataract I've seen in a TV. I've seen a couple round tubes that were poorly stored and got worse than that, but it takes work to get that bad!
Is that a Westinghouse-built crt? I wonder what year they started making color tubes? Something else I've wondered, and I've mentioned this before: in an old chassis-ID guide I have it shows the Magnavox and Westinghouse being identical, and Curtis-Mathes, as DieselJeep mentioned, seems to have used the same one as well. I've just been curious what the connection there was. Was it a joint effort, just a Westinghouse design, or ??? (I may be the only one in the world who really cares!)

for the Westinghouse Sets I think that I have the service Manual for the Westinghouse sets.
I have agreed with DavGoodin about the 2656 models tons of 6GH8s and some 4HZ8s. Yes, i think the circuitry especially the chrominance in those 2656s models are a copycat of RCAs and even the flyback looks like RCA style. someday I will look for the book and i think that X-2656-xx is a Canadian Model BTW, I have seen one with Paralell heater circuitry having two heater transformers and the heater circuitry are fused in each set of circuitry. and it also have the On-Screen Tuning Bar that two tuning bars will joining into one each time the fine tuning is adjusted. |

If I recall right in 1958 Westinghouse introduced a rectangular COLOR CRT that was the first rectangular production model, and the only available rectangular tube for about 6 years.

that is as bad as i seen.i have a rca 25axp22 that is that bad or slightly worse.the neck is busted so no repair scheduled!yours is an easy fix.it will actually fall of with no heating required.

Heck, that CRT looks like it has already been submerged with all those fissure lines throughout..should be an easy removal process especially after a little soaking if it doesn't seperate by itself first!
