Only use C0G or NP0 ceramic. Other types drift with temperature. Use mica or plastic film is you can't get C0G in the value you need. I used mostly 630 volt, but a few 500 and 250 where I could get away with it. You should use a 1500 volt or better for the 1500pF cap in the vertical feedback network.
