Hi,
Does anybody have experiance with large power capacitors.
Im restoring an old Luxman amplifier and need to replace old 10,000uF 50V capacitors. I cant tell what original once type is !!
I have checked sheets and there are three types I , II and III
Anybody has experiance to advise which Type to use ?

Choose by size and terminal connections placement.
How many options do you really have?

Physically they all same (almost) . The diff between types is 'Tangent loss angle. Type II is stippest . Does it realy matter?

I've used Mundorf MLytic AG MLGO and they are widely recognised as being of very high quality:

I don't see ESR for the Nichicon KG, however the rated ripple current ratings do distinguish between types and are very good.
If the higher voltage ratings are not too expensive go for those (check derating).
