The Sound of Capacitors

How can you get a great tone without a good understanding of what makes your amp tick? — EL34, EL84, 6L6, KT66, KT88, 12AX7, 12AT7, 12AU7, EF86, Output Transformers, Power Transformers, Capacitors, Resistors and everything else that it takes to make a tube amp sing!

Hold the horses !!!
WHat makes you so sure polyester caps weren't around 30 years ago..??
They were using polyester leisure suites back then, so why not caps??
Oh,,,,I see..now I know what happened to all those leisure suites..they recycled them into polyester capacitors... Thats why disco sounds better through those caps and hard-rock does not....
I totally get it now :lol:

In an old Wima catalog, the Tropyfol F caps are described as polyester film / aluminum foil. So they are very similar to the Philips mustard caps. Polystyrene caps with the same specs would be larger.

Durolit caps are resin impregnated paper / aluminum foil caps, just FYI.


Apparently the tropyfols used in Vox are marked TFF, while the metallized polyester (tropyfol M) capacitor pictured on WIMA's site has TFM on it. Could be TF stands for tropyfol, M for metallized and F for foil (aluminium).

Mullard mustard C296 are polyesther foil
C281 (yellow chicklets i think, axial ) are metallised film polyesther
C280 trop fish are miniature metallised film polyesther
278 series are polypropylene & paper (axial)
344 series are metallised film polyesther (lego ones)
from 76' Mullard Data Book

does anybody know what the Blue ARCO caps found in 60's Vox clyde Mc coy wah's , were made of ?

i suppose they were metallised polyesther film as well

The C280 "tropical fish" caps weren't introduced until 1964. So what do you think they were using before then?
