RCA/Thomson did have a lot of trouble with the onboard tuner in the CTC-17x-18x series chassis (as you probably knew if you were working for RCA in the '90s), but once they changed the design to separate the tuner from the main PC board, the sets became more reliable. Unfortunately, that change did not happen until the CTC203 chassis. (My RCA CTC185 did not give one bit of trouble, from that source or any other, except for a loose antenna port that snapped off the tuner PC board, from the time I bought it in late 1999 until I got a flat screen 12 years later; who knows, maybe I was just incredibly lucky, considering all the trouble that onboard tuner was -- and the callbacks it generated -- for RCA in the '90s.)

I don't know how the tuners in today's "RCA" branded flat screens are mounted, but I hope they didn't go back to the onboard design. The problems the onboard tuners in RCA's CRT sets caused should have sent a loud and clear message to RCA's R&D (research and development) department never again to use that design in future sets from the CTC203 going forward.

BTW, "Ctc-1" (the title of your post)? I didn't know RCA even made a CTC-1 chassis; I was always under the impression that their chassis numbering system started with CTC2, then CTC2a, CTC2b and so forth. I don't remember ever seeing or hearing of an RCA CTC-3 chassis, either.

They didn't- before the CT-100 there was only prototypes called 'model x', where x was a number. The model 5 is a well known example, and the precursor to the production model CT-100. I have a prototype chassis from earlier on, but no one has yet nailed down exactly what it is. Near as anyone can tell, it was a lab only experimental chassis used to explore the possibility of CPA for color transmissions.

Tidbit: CTC-x only refers to the chassis, sets normally had actual names. See the picture in my signature- Director 21 using CTC-4 chassis, Wingate using CTC-5 chassis, Anderson using the CTC-7 chassis... Ed Reitan has a good site that explains all of this with pictures, he has most of the early RCA stuff up to CTC-10. Check it out:

I'm not aware of a 2A, but the 2B is the chassis belonging to the model 21-CT-55 receiver that replaced the CT-100 and actually uses a modified CT-100 chassis. The changes include a different high voltage and scanning section to drive the larger 21" round picture tube.

Is there a CTC-3? Now there's a trick question you can pull on your friends!

Early color trivia time: In the 21-CT-55 receiver, the main chassis was the CTC-2B, and the convergence panel was called CTC-3 since it was a seperate chassis connected to the main one with a harness. Technically, there is no such thing as a receiver chassis with the designation CTC-3. So it exists, just not as a set by itself.

Correct! (And nobody noticed that I had mentioned that in my earlier post

)...
