WIMA and RIFA have very good caps.
WIMA have some different Polypropylene caps,
some are slightly better than another, but will cost more.

If you want a good MKP (metallized PP) cap for Audio.
Use SOLEN SCR axial cap. Reasonable prize /uFxVolt. (money/CV)

(sorry, did not find some pictues of SOLEN Axial Caps)

Default Hearsay only.

I havent tried them myself, but have read that FKP type caps. i.e. polypropylene and foil WIMA caps are the way to go if you don't want to go way esoteric and expensive. They are the light blue ones with yellow epoxy fill. They make no claims for audio usage but are a rock solid no-nonsense cap for high frequency, high current and pulse usage. Many other caps used in such a way get all hot and bothered.

Exactly what caps are you using now? If you are already using FKP1's then you are probably about to pass that point in the money vs. results graph that takes a sharp bend for the worse.

GP.

Hi circlotron,
I found the red coloured Wima MKP 10 better sounding.

I have a Electronic Concept cap in my hand! It feels as good as it is. EC makes the best(?) caps in the world. They can be seen in heavy duty switched power supplies.

Check out how much current they withstand!

Default CAPS

Hi,

Assuming that's Newcastle in the U.K. i can highly recommend the ICEL range of polyprops as used by some major tubeamp manufactures.

I noticed RS Components sells them.

For the more esoteric caps and parts you could check out this US supplier,they have some on sale with a 30% discount:

PCX

Ciao,

Not really knowing but my hunch is no. The major constribution in the sound are the tubes and the transformer, I think.

Nelson Pass discussed this in an another thread and I believe his is right.

Capacitor Distortion

You don't have to replace all of them at once. Just try the coupling ones first and hear the results. From my experience good caps make a difference. And Hovlands are a pretty good choice.

It's a shame that I don't have the camera here. The legs are 1 mm thick!

Check the data for 5MP12!
