FYI: This set is 'in the system' and appears in the Living CT-100 list http://home.att.net/~pldexnis/input/...mbers_List.htm.

In that baseball game screen shot, Kirk nicely captured the 'look' of NTSC color on a 15GP22 driven by a properly calibrated CTC2 chassis. What you see doesn't duplicate the image on the 15GP22 of course, but the 'flavor' is there.

Using just the published set up procedure, it is possible to achieve virtually perfect vertical convergence on a CT-100 as the photos show, but apparently not too in the horizontal direction. Again, as the photos show. This follows statements in early RCA color TV literature that basically says to not expect perfect convergence, due probably to a design issue rather than simply a 1954 servicer's ability and inexperience.

I have seen this set in operation and the gray scale tracking is superb.
