GK MB500 (MB2-500) Supply Voltage Change

[cagincet]

Davidprice is right (post #15), there are two jumpers for MB Fusion.

First one can be seen is on the picture earlier in the thread, ice power board (blue jumper in my case)

Second one is near the power cord input and the fan (black jumper in my case).

By the way, on the power board under the fuse, there is a fuse figure that says

250v
T 5A H

No indication to use T 2.5 A, but I will use a T 2.5 A anyway, to be safe.

This is good too:

Hey guys, just bought a GK MB200 and it's wired for 220V, but the manual says to use 230V for Australia, so I wish to change it to 230V operation.

I found the input jumper, which has 3 pins:

a) 3
b) 230V
c) 115V

The jumper was originally covering pins a and b. (3, and 230V)
Which pins should it be on for 230V? Does it just cover the middle pin, like I've done in this picture?

Or does it need to cover b and c (230V and 115V)

Thanks!

Leave it as it is, there is no significant difference between 220v and 230v.
I used for years at 220v a marshall with a power switch set to 240v
