Film vs. Ceramic Caps for higher voltages?

[toxcrusadr]

I'm working up to restoring my first old TV, a '50s Admiral radio/phono/TV console. At this point I just have a list of caps to replace, so I can't tell you where in the circuit I'm referring to, but in general:

Does it matter whether a cap is a film or ceramic type for most applications in TV circuits? Aside from the electrolytics, I'm talking about values like .047@600V, .033@1000V, .02@1600V. At voltages up to 400 or 600, film caps like orange drops are fine, but once you get into the higher voltages they get expensive. Can I replace films with ceramics if ceramic is cheaper?

IIRC, I have these on my parts list because the originals are films and I assumed they needed replacing. I'm guessing I left the ceramics as is for now.
