color stripes on screen (slyvania roundy)

[technicolor]

well, checked all tubes, surprisingly only the high voltage tube was barely weak, low end of green, so i replaced it.

Colors are all messed up, when i dial in the fine tuning, i get what appears to color stripes on top of a back and white picture.

It also has a crt booster plugged into it.


any ideas, please tell me recapping this will fix this
