Hi Guys
Champ81: What values are you looking for? In cases where you want long leads, as we always do for hand wiring, you end up going to high-voltage types (1kV+) and maybe to safety caps. Myrata has many long-lead ceramics that are typically X or Y tolerances.
When you do the searches at Digikey or Mouser, select only one parameter at a time and then 'apply'. Selecting too many restrictions often brings back zero results.
With the short-lead caps, use bus wire to extend them to reach the terminals, or solder it across a small resistor then cut out the resistor.
Mica is more neutral compared to ceramic, so you see hobbyists swapping a mica for the 270oF treble cap in Fender EQs. In a Marshall, you might hear a difference, but maybe not, as the EQ is less effective due to being cathode-driven AND the high IM of Marshall's wiring arrangement could easily mask the cap tone change.
Makinrose: The Ys fall between the Cs and Xs grit-wise. The differences are small, and as I said above, value-dependent - more noticeable with high values than with low.
In my own amps, I generally use plastic caps everywhere in the signal path, and even in the kits. The REV Reverb kit may be the last one with a ceramic in it, but it is <100pF so not too disconcerting
