Thank you all for your help!
This MS-10 now have a nice story to tell.
At first, I thought the transformer was fried because of that it had
american power cable and the fuse was very blown (The original fuse was
replaced with a 220v 1A fuse). Then I found out that the transformer
wasn't even properly connected, it was wired up at the secondary side
directly with both 220v and the mainboards cables and the primary side
wasn't wired at all. Not even used (probably someone have tried to
replace the 110v transformer with this 220v transformer without any clue
how to do it). The regulator 7915 and a capacitor at 220microF seemed to
be the broken, so I replaced them and connected the old transformer
properly and voila!.. It's alive!
Again, thanks a lot!
(And if there's anyone having the MS-10 schematics and access to a
scanner, mail me!)
