Default What type of capacitor should I use?

I am not referring to the electrolytics, those I know need to be
electrolytic caps. I am referring to the inter stage caps, such as .01
.05 .1, .005 and so on.....

The object is to replace all the caps in an old tube radio, or any other
tube stuff.


well, if you must replace them with more modern components, a decent
ceramic capacitor should do fine. From what I have seen, ceramics were
common in gear made in the 50's and 60's because of their small relative
size and reasonable consistency in manufacturing.

You should be able to order them from companies like Digikey, Mouser,
etc.. Just make sure the voltage ratings are high enough, and you
should be ok.

I've seen on-line "photo piles" of before/after restoration efforts in
which modern components were "hidden" inside of hollowed-out components.
Maybe you can stash a modern ceramic inside of the paper/wax tube, and
seal it up with a bit of hot glue...
