Electrolytic caps

[Swankmotee]

Anybody got experience with comparing electrolytics in the power supply for best tone? Is there one brand that sonically outshines the others? I’m getting ready to recap my 73’ 100 watt Marshall and want to get as close to the old Daly’s as possible. Thanks in advance!

I doubt if you’ll find any of the experienced gentlefolk here who will buy the idea that filter caps affect an amp’s TONE. Filter caps are entirely functional. When they work, you don’t notice them. When they don’t, you get hum, poor bass, crosstalk, and other malfunctions.

Well Xitan I have tried many through the years and they definitely made a sonic “feel” difference so I’m just wondering what the current brands which are few have going on.

after a recent thread on el34world.com I'm thinking of ditching elytics completely for these kinds of caps:

costs a few bucks more, but they'll last indefinitely like other film caps, so I'm thinking it may be worth it to guarantee the longevity of the build.

Colossal built an amp using that type of filter caps.

If you want it to sound stock then I use F&T brand filters, if you want it to sound better then stock yet not go the massive expense of HI Fi type audiofile filters then just and in parallel across your first preamp filter a .22 orange drop and a .022 orange drop both rated for more then your supply voltage for that preamp stage.

SteveM uhhhh no. I’m looking for stock and F&T’s, JJ’s, and the baby blue one that the name escapes me sound flat and varying degrees of one dimensional thus the point of my original question. For a brief moment in time SoZo was making an excellent sounding Daly clone but stopped production. CE offers a very low ripple can that I recently used in another 73’ Marshall that sounded very good overall so more than likely I will end up using them again. The ones I’m replacing are Elna’s which are audiophile types which are fine but too stiff for my tastes.

I'm not sure what you really want here.

You ask for a cap that provides "best" tone - that's highly subjective. Then you ask for one that sounds similar to the old Daly caps. Which is it? You're asking for opinions.

Then, you dismiss the opinions of others that you apprently disagree with, cite your opinions on what caps you like, etc.

Sounds like you already know what you want.

So what is the point here?

yeah and I'm firmly of the same opinion of xtian here, as the power filtering caps aren't even in the signal path, and from everything I've read/seen, they have only detrimental impact on signal path if they're not filtering enough, and they add crappy tone/hum, but if they're working, they're transparent. I'd love someone to show me actual data that proves otherwise.

Biggest difference from one electrolytic to another, ESR

Are these like a cap can, with multiple caps in one package? The data sheet for the 4 pin version doesn't show a pin out diagram that I could find. Is it just 2 independent caps in one package?

nope they're film capacitors that can take the high voltage needed and can get into the range we use for power filtering. Best of both worlds. Just costs more. A 40uF cap costs like 8-10 bucks vs 5-6 bucks for the electrolytic types.

Maybe Dave (colossal) will see this thread and respond but I remember him talking about the short leads being a problem for soldering into the board.

The main difference is life expectancy I would assume with film cap vs e-cap. Solen fast caps are good but physical size makes exacting pre-planning a must.

Yes just a single cap.
It's common that larger components intended for PCB mounting have additional terminals to provide a better mechanical fix to the board, eg and so avoid the need for adhesive/goop/ty-raps.
Those additional may or may not be electrically connected to the component.
