Zenith6S321 07-07-2013, 09:55 PM Cool, looks like you are making good progress. Glad to see your CRT is good! When I get some time I'm going to try using the Sencore VA62 alignment procedure to try to get rid of my vertical white line. Good luck with yours. Dave miniman82 07-08-2013, 02:39 PM Poor sync can still point to horizontal issues, make sure you have all the correct voltages. I just use the procedure in Sams, it's a good one. wiseguy 07-08-2013, 03:49 PM ... miniman82 07-08-2013, 06:24 PM I am Curious what type, or part number everyone has used for the ALL 250uh peaking coils, since there are many and I was able to get what was in the sams Meissner brand, "19-3250" I didn't worry about originality with those, I just shopped at Digikey: From phase detector to reactance tube grid: M10101-ND (1 piece) Matrix output to CRT: M10093-ND (3 pieces) Y-line, near delay line: M10082-ND (1 piece) R-Y demod/amp: M10083-ND (2 pieces) Q demod: M10098-ND (1 piece) and M10127-ND (1 piece) Y-line near 2nd video tube, and matrix power input: M10106-ND (5 pieces) ^ That's from my CT-100 resto, but the 2 chassis are similar enough. I put the same coils in both my CT-100 and 21-CT-55, the colors on the screen were very nice. No one will know you didn't get correct pi wound coils, it dosn't appear to make any difference. wiseguy 07-20-2013, 03:42 PM ... wiseguy 07-20-2013, 06:22 PM ... Sandy G 07-20-2013, 06:54 PM But you're SO close ! I wish I had, 1) a '50s color TV, & 2) the technical knowledge/ability to work on it & NOT kill it.. wiseguy 07-21-2013, 01:34 PM ... wiseguy 07-21-2013, 01:35 PM Well here Sandy, you can take this one on. :) But you're SO close ! I wish I had, 1) a '50s color TV, & 2) the technical knowledge/ability to work on it & NOT kill it.. Sandy G 07-21-2013, 02:01 PM Danke Schoen, but do the words/phrase "Bull in a China Shop" mean anything to you ?!? wiseguy 07-21-2013, 05:57 PM ... Zenith6S321 07-21-2013, 06:50 PM Nice progress! The current through the fuse in my CTC2B is also right around 206-208. I think I finally have a good IF alignment, but I still have a little more work to do on the color alignment.

I'd guess better camera let you change that. |
