Simple question regarding converting chipamp from 110V to 220V

[maurycy]

Thanks for helping newbie.

I have the following wires for the mains:

black
black
brown
white
white
blue

Currently, I have black-black-brown tied together and white-white-blue tied together for 110V. How do I re-wire it for 220V?

Thanks.

You are best off looking at the side of the transformer, at the wiring label and telling us which wire is which, to avoid any possible risks.

Will do once I get back from work. I will post a picture or schematic if available.

Thanks.

Dont worry about the picture, the coulor codes will do.

Finally had a chance to take the case apart, un-glue the trafo and take a look at the code label. Here it is:

White x2 0V
Brown 120V
Blue 0V
Black x2 120V

The other end is:

21V Red
0V Black
21V Yellow

So for 230 V connect transformer blue to the mains cable blue, transformer black to mains cable black or brown and transformer white to transformer brown.
