CTC 11 advice

[Travis]

Hi, I have been looking around this site for quite sometime and have never really said anything. I have been accumulating dead TV's with the thought that I am going to let loose and fix them all shortly.

I had decided that I want to start with my CTC 11. It's in the bedroom and color, so it should be fun to watch. It is clean. The only damage I can see in the antenna terminal is broken. T have checked the CRT and it tests very good. I did notice a hairline crack on the base and that it is starting to get loose. I am seeking some advice on how to proceed. I have checked the tubes and found seven of them to be weak or bad. I haven't powered it up at all. My variac is waiting by it, but I don't want to kill it. It looks like some of the caps have been replaced. Could I replace the bad tubes and try powering it up slowly?

I will post a pic of it soon though.

Thanks!
