When I first restored my 9VT1 I used ceramic caps to replace the high voltage caps as that was all I could find and I did not know wehere to get the tubular ones. They worked fine except for the vertical. I could not get proper linearity until I doubled up the caps in the vertical circuit. It had me stumped for quite a while. I eventually replaced the ceramics with tubulars and would not attempt to use ceramics again in this application.

I'm Convinced
 

After reading your posts and looking at some of the links, I'm convinced not to go cheap with the HV caps. Especially when I compare Phil's 19A12 picture with what I had when I picked up the set two years ago.
