re: AU-217

This is a great little amp (big in sound).If you can find one in mint condition you'll be impressed by it's accurate sound.I'll confess that I've been messing around with Quads,vintage Marantz,Revox,Apt-Holman,etc.and this amp really impresses me and it's the one I've kept....nearly perfect for a 100ft square room.
Works better with 10' or 12' woofers on your speakers.I use it with a pair of Advent Legacy III and it sounds perfect to my ears.If you want a more softer sound of same quality and punch go for the AU-317,also a beauty.These amps and all the AU series were developed while Mr.Takeshi Nakamichi was president of Sansui.I don't know if he has any relation with the excellent products of the 80's golden period of the Nakamichi brand.

Replacing Electrolytic capacitors in a Sansui AU-217 (not MKii)

I am planning on replacing the electrolytic capacitors in this unit, it is making a static clicking sound, so I unhooked it before it burned out. I understand it is the caps as they wear-out over time and this unit is about 35 years old, this seems to be a common problem. I have limited knowledge of electronics, but am learning more.

Does anybody have a service manual for this unit that lists all of the caps. The one I have ony list (11) caps there seems to be a lot more I was looking only to replace the electrolytic ones.

What is a good brand? I have been looking and matching the current ones to Elna, Nichicon, Mundorf, and Cornell.

Has anybody increased the mfd of the power filter caps, I was thinking of either 10,000 or 12,000 mfd 50 to 80Volt range; would this help anything or should I stay with the 6,800 50Volt ones?

Did you eventually recap your AU-217? If so please describe.
