So after looking my *** off, I found that rs-components, has almost al the panasonic fc series.

I`m still not confident in the de ( ?) coupling caps 0.1 uF, would mkp wima`s be nice for that?

And I can`t seem to find 4700uf and 15000uf 35 or better caps, which comes close to the pana`s.

btw, nichicon any good?

anyone got more tips?

Else I will see if I can get my hands on bc components.

God, you must get annoyed by all these questions... - sorry-

Sanyo MV-AX series are worth looking at. Low impedance 105C.

I used them in a switching regulator for pentium 2 processsor core voltage which called for <100mV ripple at 30A/us. Switching frequency 300kHz. This Sanyo was one of the few that really worked. Only OSCON was better.

In digital part Elna RJH is also worth a try, in analog supplies Pana FC is a bit better for my taste.

Do those caps from sanyo come in large capacities? Or is that for the 0.1uf nice? Are the oscons, in the same leaque as the FC panasonics?

I found a nichicon LLQ series 4700uf but i don`t know if the esr on that one is nice, any guidelines on esr ratings?

I finaly found a rubycon 15000uf usp series, but as with the nichicon, I don`t really know if this is any good, I don`t see "low esr" mentioned on the data sheets. Since I cannot completely interpet the esr rating, I rather hear from u if it MIGHT me nice.
Guess I will read the "picking caps" page again.

If I use one of these, while al the other caps are panasonic fc, will that be redundant, because I will put in 1 "bad" cap, or will it not deteriote the ps, as a whole?

Sanyo MV-AX are frpm 1uF and up electrolytics.

I'm using 1500uF 50V Sanyo's in my 5 channel gainclone. I can hardly see any noise at 50mV/cm on my scope.
