It looks like three caps(C22,C23 and C24)were replaced at some moment.

Ah - it reminds me of a problem that I had on my M10. One of my (almost 50-year-old) caps was damaged, and the capstan motor stood still.

The schematics say they are 0.5,0.1 and 0.5MF(non polarized electrolitics) rated at 220Volts,the ones in my machine are the correct value but rated at 630 Volts(sure it doesn´t hurt the machine).Can this be a later upgrade?

I'm not sure... is there a year written on the caps? Or anything like "3/62"? In my M10 (no M10A, unfortunately ) there are 630 V types, built in 1962.
I am no skilled engineer but I guess the more Volts they have, the better it should be . They might live longer.

As far as I remember there might be capacities which are slightly different from the schematics - in order to get a smooooooth running capstan motor. (Unfortunately I myself lacked the suitable measuring equipment - three amperemetres - so I just replaced the old caps with new ones of the same dimensions.)
As I learned from a radio broadcasting engineer you can replace them also by new (as it's called in German) "Folien-Kondensatoren" (I don't know the English word, sorry).
