Wayne, great writeup of your personal experience evaluating the original wideband, low level chroma demodulators of the original CTC2 chassis versus the narrowband, high level demodulators of the CTC4 and later chassis. You suggested that the performance improvement of the CTC2 was probably wasted on the CT-100's 15GP22 small size. Well I had an opportunity of verifying the obvious superiority of the CTC2B over the CTC4 in 1964 when I had both TVs converted to the much larger, much brighter 21FBP22s. I described the comparison in my first 21CT55 thread of Feb 28,08:

"When I bought my 21CT55 for $50 in '64, I brought it into the house after I got it working and ran it along side my Dad's old CTC4 he left me. Both had 21FBP22s so it was a good comparison of narrow bw color R-Y B-Y vs. full bw color I Q. The extension of full color into fine detail on the CTC2B was startling! Color persisted in fireworks until extinction which I never saw before. The CTC4 fireworks turned into white long before extinction. The CTC2B carried full color way into the shadows, the CTC4 went gray to black. I kept the CTC4 in the house for the kids but brought the CTC2B back to the garage workshop for further study. Ease of working on the chassis and CRT "forced" me to destroy the cabinet and configure the remains into the vertical chassis configuration I am blessed with today. That’s alright with me. I respect the original CTV restores but that’s not my thing."

I'm looking forward to view the screenshots of all the restored tubed roundys out there displaying DVD test patterns, direct or thru a good modulator. Hopefully a few will be 21CT55s............Tom
