"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." - 1993ctc175
IIRC - There are two filament transformers on the "back deck" which protrudes out from the chassis under the CRT socket. All the pots are located there also. That does explain the 6GH8's used as opposed to the 5GH8 seen in the RCA CTC22 and 36. I also need to see if that tuning feature exists, but I do not remember it. Maybe the CP88B48 had it, but not my CP88A19. I attached the Consumers Reports for the year these were sold is amusing at best. It seems the Motorola and Westinghouse were the two most expensive sets. Have a look at the "Color TV Repairs" section. I'm guessing RCA and Sears did poorly due to over-use of service contracts, maybe the same is true for Packard Bell and Curtis Mathes (these are almost non-existent in this corner of the US), which brands everybody seems to be aware of anyway. ![]() I will open it up this weekend and post some photos.

Westinghouse CP88A18 inside
Here is the rear of chassis - the bottom - and from above (the 'lytics will be a cinch to stuff
Attachment 172975 Attachment 172976 Attachment 172977 The inside without the chassis is most revealing. This set was the most basic, judging by the other possible cutouts. I even had to add the zenith speaker on the right...such a shame to waste a prepared opening like that. Notice the lead skirting on the CRT. Westinghouse did nuclear energy back in the day and this set has numerous clues to that awareness. ![]() Attachment 172978 A telling CRT label - and it tests 100% with good cutoff Attachment 172979 The right jig for 19" kine - a 5 gallon bucket with foam pipe insulation Attachment 172980 We have liftoff Attachment 172981 Nice and clean Attachment 172982 Bright and safe again!

Boy... Westinghouse didn't want any lead exposure. LOL!
I see the CRT is a replacement. GE, code-date 1973. I always wonder when I see replacement CRT's that aren't much newer than the sets. Obviously on this one, the original failed within 5 years. |

Lets hope that it was replaced under warranty. I rarely replaced CRT's in the years I had my shop.

Yes, Regarding to the Chassis of the Westinghouse Set this is Exactly the Chassis that I have seen.
Like I said, When I was a high school student I have fixed a 25" Westinghouse for my Homeroom Teacher. Also, I have a Service manual for the Westinghouse Sets |

probably not... manufactures were kinda stingy on the warranties. I bet 2 years max on the CRT. We rarely replaced one in our shop either. We'd come across some bad ones, so my Uncle would try to rejuvinate first, so the ones that got replaced were really bad.
Whenever I see an old set that had the tube replaced within the first 5-7 years, I always wonder if it was a repair shop running up the bill. Especially on roundies (those 21FJ's were bullet proof) I have a 68 Magnavox with a 1971 RCA replacement tube.. so the first tube didn't last 3 years, but the 2nd one tests good after 40? hummmm..... |

Magnavox, Philco and GE sets had some of the shortest-lived CRTs IMO.
RCA (then Thomsen) built them about 3 miles from here in Lancaster. RCA's seemed to last reasonably long enough, except the early 21"s when reds got weak first. The years I worked in the "business end" were 1979-86. The only replacement CRTs I remember were (starting most desirable) Sylvania, RCA, Maganavox, Channel Master My long-time living room set was a Mag T995-01 touch -tune ca. 1977. Rescued it as a trade in 1985 with bad CRT (no surprise) bought a Maganvox replacement (Philips?) and it lasted till the set's end in 2005...Hmmm indeed! testing all the tubes in the W-house tonight (methinks there is a single OEM tube- ???) |

My dad had the surgery. He said it felt like a grain of sand in the eyes for a few days, but he had drops for that. He noticed a vast improvement in his vision the next day. As soon as the first eye healed, he had the other one done.
I've had eye surgery, too. Not cataracts, but Radial Keritotamy. Slits in the cornea that caused the optics in my eyes to shift correcting my very bad near-sightedness to 20/20 for almost 25 years. Now, I am on reading glasses. On CRT cataracts, I use the hot wire method. Nichrome wire and an electric train transformer. I go really slow, and it slices. |
