CTC-9 Winslow

I picked up a CTC-9 with excellent emissions on the original (or RCA replacement) 21CPY22. 2/3 electrolytics cans had bad ESR, so I replaced all three, along with a good amount of resistors which were 20-30% out of tolerance. I also changed out all of the maroon caps/wax paper caps that were present in the set. I randomly pulled a few and the majority had some sort of leakage.

On power up, I'm not getting any video through the set. I can get a very faint blue raster if the screen and drive are turned all the way up as well as the brightness. Green and Red are not visible. (Though there is a bit of green because of a purity issue) There isn't any sort of static on the set. Any troubleshooting ideas? I'm not sure how much troubleshooting I can do on the bench without the picture tube connected. It's a PITA to work out of the back of the cabinet.
