Nippn Chemi-Com

Does any one know of a source for Nippon Chemi-Com electrolytics,

I am after the Black 10000uF (M) 63v also has SMH 85C
code on side = 2X07041M ?

I have substituted them with Nippon Chemi-Chem 10000uF (M)
63v KMH 105C code = ODAO4L These are brown and larger

but are not as good. Any ideas ?

regards granville

 

what about them is not as good?

 

Graham, They form the power supply of a four channel PWM
amp (LC Audio) There is a little more hiss from the drive units(with no signal) when compared with the original ones. The treble is also not quite as pure as it was. A little bit cloudy ! I don't know the difference between them apart form temp rating.
Any help or thought would be appreciated.
