1948 7" Teletone Problems

Hello everybody- This my first post so I hope everything goes well. Thanks in avance for any help. I am working on a 1948 Teletone 7" electrostatic deflection set. I have completely recapped the set and brought it as far as you see in the photo. I have replaced a lot of resistors. I have checked all the tubes. As you can see it has a foldover problem. Can anyone give me advice on how to repair this? Thanks again! Alex
