The CTC-4 was a sensible simplification from the CTC-2, and a good first 'from scratch' 21" color set chassis, but the CTC-5 was RCA hitting bottom in terms engineering cheapness....It was a poor design that often struggled to produce 18KV of high voltage when the (known to be somewhat dim when driven to spec) CRT it drove expected about 25KV give or take about 2KV. The CTC-5 had issues with blooming (HV becoming loaded down by picture, and raster changing size, accompanied by loss of focus), problems with brightness and contrast interacting (worse on some versions) such that it was hard to set them, etc.

So was the "resurgence" in quality in the CTC-7 due to the new 21CYP22? I'm guessing they had to re-engineer the chassis for the new tube. I didn't know the CTC-5 had these problems. With this in mind I'll never specifically go out and buy one, but if one comes my way cheap or free, well...
Thanks for the reply.
