What's new

I recently got a MS9-29 15k/24k auto switch chassis, it works all good without issue except little bit typical jail bar on the left side due to old caps.

So I was planning to recap it, then I found out that there are two capacitors are different from other MS9-29 chassis I dealt with before.

First one is C956, on other MS9-29 chassis I have it's a 680µF 10v, but on this auto switch chassis it's a 1000µF 25v(a nichicon vr series, seems untouched).

The other one is C955, on other MS9-29 chassis I have it's a 180µF 25v, on this auto switch chassis it's a 220µF 50v, when I soldered it off, I noticed the joint was more fresh than others, and the cap I can't tell its brand, also it's a 85c, so I believe it was replaced before.

Can anyone confirm what these two caps C955 and C956 should be on a MS9-29 15k/24k auto switch chassis? Thanks.
C956 680uF 35V
C955 220uF 35V

The caps on mine don’t look original—the C956 has black marker on top of can

Those caps were replaced with china caps, the original ones on all ms9, including the auto switch model, are:
c956 : 680uf 10v
c955: 180uf 25v (but you can put also 220uf)
Replace them with something good like nichicom UPW or UHE or rubycon YXF or YXJ series.
