Tubes/parts needed to get a Philco 50T-1406

[mpatoray]

Hi all,

First of all I would like to thank all of you who have helped me on this set. Some things got in the way so it was on the back burner, digging back into it soon and I have a question, I was told to replace all of the mica caps in the horizontal and vertical section as i can not get things to stay stable and all other paper caps have been replaced. For the replacements what type of capacitors should I order.
