I'm modifying a Sansui TU 9900. It apears the main signal path caps are a Non Polarized 10uf 16V. I'm wondering what would be the best cap for best sound.I have some Muse BP 10uf 50V but I'm wondering if Solen or others might be better?
Also, should I also bypass them and, if so, with what?
Thanks!
Follow Ups:
My choice would be a Blackgate of the same rating. There are also some fine 10uf film caps but they are both expensive and large.
Personally, I like Nichicon Muse caps a lot. I'd give it a try first. Putting a film cap of almost any type that's 10µf may not fit. I have seen cases where people have tried to fit a poly cap in the place of an electrolytic, but left hugely long leads on the cap, and with the cap floating well above the chassis. In those cases, they may very well pick up more noise than they prevent compared to a good electrolytic.If you want to bypass the muse (which I do often), put your favorite non-expensive 0.1µf poly cap across it, preferably under the board. It's easy to do if done at the same time as installing the poly cap, you have the leads to work with. It's not necessary to try to wrap the leads of the two caps around each other, a decent solder bridge is enough.
and really nothing but DC from being amplified by the preceding stage.I have replaced many of electrolytics with polypropylene caps and have never had a problem with noise being picked up at all by the longer leads. The argument more or less comes down to dielelectric absorbtion factor in which most electrolytics measure quite poor compared to a teflon,polyprop or polystrene cap..Electrolytics belong on the power rails not in the signal path..

I have never used blackgates but the hype sounds good. If i had 200 bucks to blow per reservoir cap I woulds have more recorded media for sure..So far my circuits have worked quite fine with the standard run of the mill Nichicon Vx/Vr, Nippon Chemicons and Panasonic FC's..
...usually, a combination of Panasonic 'lytics in the 1st poles and motor-run and Solen 'propylenes in 2nd poles of high-Voltage supplies. I use BGs for smaller requirements--decouplers, cathode-bypasses, etc.
