Guys,
I appreciate your comments. After a good night's rest and a clear head I have selected all 630V TDK caps with 2 exceptions. 1 is the 1KV 1500pf cap used in K5 the Vertical Feedback couplet, and the 82pf cap used in K6 the Horizontal AFC couplet. The 82pf cap that I could find was a TDK 100V or a Kemet at 200V. I know I could always use a mica cap. BTW, all the caps are ceramic MLCC's and COG/NPO type.
Here's a link of the typical TDK cap that I'll be using:
