Converting Markbass Micromark input tension (220> 110v)

[bajiton]

Hello the community,

I have a markbass MicroMark, purchased in France in 2007, it has a 220v input. Now I live in a country where the voltage is 110V (127V exactly ..., Brazil), so I would like to modify its input voltage, and switch to 110v (consider the remaining 17v as a present).

Markbass clearly states on its website that the voltage should not be changed, blah blah blah blah, this is only a marketing argument, not really suitable for the itinerant musician, who should seek other brands rather than markbass. I read here on this forum that it is possible to make this change, but I did not find any clear explanation, other than changing the input fuse (now a 250v - 10A) and possibly change a jumper (JP).

Here is the internal circuit of the beast and the details of the jumper:

So, what should I do ?

Can somebody provides me a picture of the internal circuit of the 110v US version ?

Thanks !
