There is how many REV? What are the changes between all the revisions? REV D, etc.
" One more amp " is going to be probably able to answer all my questions.

Good Afternoon Chaplin, I am currently away from my desktop but I will try to be of help none he less.
As for revisions I have found mostly parts lay out being changed with minor part value changes to reflect current preferred product construction.
BUT, this will have very little to do with cap changes that you need to do to protect and restore your amps.
Specifically I see 5 2200ufd caps rated at 16 volts that need to be replaced inside your MS-250. There are three in a cluster mid section of the board in the power supply side of the amp. Then there are two more located in front of the fets and in between the power transformer.
These are your main concern at this point. The extra two caps in front of the fets are special to your MS-250 and are not used in other models of these MS series amps.
Other than that everything stated in the tutorials elsewhere here on the site are totally acceptable and applicable to your amps. The MS series are extremely similar in design, and just scaled up or down to fit the power
output spec for that particular amp.....I hope this helps, and if you need more info please PM me, I answer all PM's as promtly as possible......C
