Hi!

I got a MS9-29T in my Capcom Impress cab. Everything working ok, but I get some interference that could be cap related.

After reading Mike Moffitt’s great guide to MS9 (http://mikejmoffitt.com/pages/ms9-hax/) this looked like it could be worth a shot:

“What does set this model apart - and I still don't understand why - is that the primary section does not feature the following capacitors: C994, C992, or C991. The latter two are X-capacitors. If you use this chassis in another cabinet, you are likely to experience interference. You can use this chassis in other machines with no trouble, but populate those caps if you do”

Does anybody have the correct values for these capacitors?

Dirty pic from ebay... I am missing those blue bastards on mine.

For those who are interested, here are some info regarding this issue.
C994, C992, and C991 are ceramic safety capacitors used to reduce EMI/RFI interference on the AC-line. Caplist under is for the MS9-29SU chassis.

And the cap I am thinking about ordering from mouser. Both a X1 and Y1 safety capacitor suitable for industrial use.. Should be fine for my MS9
