The sweep tubes are good for sure. I tested the rest and like you mentioned they are very weak which is not surprising being they are all original. I will be picking up some replacements in Orlando next week. The IF amp, video, and the color outputs were very weak indeed. . I did remove the multi pots and clean them, they did have tin whiskers. I did clean some of the circuit board I think at this point though I'm gonna take a good air blower and see what I can do with that. It appears that the electrolytics are still good. In looking through some information that I did have on a GE roundy, the color demod is almost the same and if I need to align or rebalance that will guide me. I am finding a number of high reading resistors (the kind I call wooden resistors). They are the type I will find in 50s and 60 radios and amps. These resistors have slightly rounded edges and muted color bands, a far cry from the Ohmite resistors that never seem to age. More on this project when I get the tubes.
