This cbs Columbia has got to be the worst set I have ever worked on but then again it's 66 years old so it was expected. First the verticle, no sweep, then it looked good then the horizontal, no sweep, then after replacing Micas in the verticle and the horizontal I got both back but the picture was very unstable pulling to the left and right and the horizontal lines coming and going and the verticle rolling and unstable. Finally I realized the problem was in the IF so I spent about an hour and a half adjusting it out since I couldn't do a real alignment not having the proper gear it looks like I finally got it. You never know what anyone has done to an old TV set befor you get it or what screws or adjustments were touched. So now comes running it for a certain amount of time to make sure there are no more surprises that creep up.
