After two attempts and hours of tweaking I have working set. Nick was so right, the CTC2B is very tough to align, at least for me. Here is a picture of the sweep response from the tuner crystal to the video detector test point. Not as high a peak at 41.65 as RCA shows but the others freqs are not bad. I ended up using the Sencore VA62 10 freq multiburst to do the video traps and bandpass alignment. And I finally realized my color bar generator needs alignment. So please ignore my info on the RCA to VA62 color comparison. I used a Heathkit IO-101 I picked up at this years ETF convention to get the correct color bars to do the color alignment. Here are also some pictures of my flyback temperature using a fan to keep it cool and leaving off the corner cover as a vent. The fan keeps the flyback just warm to the touch after running for hours at about 205mA. And a pic of some cartoon color.
