You're Getting There!
Wayne, seems the major part of the CTC5 restoration is completed, looking good! My Dad's CTC4 of 50yrs ago was my first adventure into color TV and was the first narrow-band chroma RCA made after the CT-100 based 21CT55. It used the same 21AXP22 but had at least 10 less tubes. I recall that the CTC5 was designed to eliminate some of the CTC4's worse problems but it remained narrow-band. Did RCA or any other tubed roundy maker return to the original NTSC wideband, low level chroma demodulators?
As you continue refining your CTC5's picture quality, please continue posting your screen shots in the highest resolution. I use DVD test disks to evaluate all my CTVs and compare their PQ against the highest performance modern ss CTV that can be accommodated in my tiny lab. My favorite DVDs are "Digital Video Essentials" and "Planet Earth". Obviously the goal is to get the TV being evaluated to produce the closest PQ to the "Lab-Standard" PQ and capture the comparisons with a quality digital camera in JPG format....Tom
