Wax-paper, oil -- polycarbonate or mylar, e.g. Sprague "Orange Drops".
(My opinion. Others may object quite vehemently.)

Mica - Mica or silvered mica. These rarely need replacing. But be awa
many of the larger "domino" capacitors are actually paper. Generally,
values over about .005 uF (5000 pF) will usually be paper.

Cheers,
Fred

This one just asks for our "Happy Ears Al" ...... !!!!

Just try and listen (to the caps , not the stories) .
I don't like (almost hate) MKT = 1/2 the orange drop range ....
But you might just like them .
Your happy ears might differ from mine ......
Just don't stuff an amp with just one type !!

I forgot to mention that I´m restoring now some old test equipment,not audio,
"the sound" really doesn´t matter.
There are tons of info about caps and sound.
Sorry if this is off-topic.

En ese caso creo que es bueno usar polypropylene regular de
cualquier marca, en lugar de los de papel y cera o aceite.
Con los modos modernos de fabricar capacitadores, es dificil
hacer los que no son fiables.

Hay nuevos de mica que son buenos y ecomonicos.
