Sorry I don't have an e-mail listing, however i will be back to this web site often to catch up on what's happening! Firstly, I am a amp repair tech that works at a music store, and have done this mod. often. Basically, you need to check and see if your current power transformer is adaptable to 220 current. If so, all you need to do is some basic rewiring from the power supply board to the unused windings of the transformer. Otherwise you are looking at buying a new transformer and installing it, which although it is a relatively easy mod, it can be expensive and it may be cheaper and easier all around to buy a seperate power transformer that you plug your amp into.  
this also saves the hassle of undoing your work if you ever return to the states! Hope I was able to shed a little light.

Todd,  
thanks for the help...  
I am currently using a trans-  
former, it's a little bit of  
a hassle, but you're right...  
never know if I'll come back  
or not. I'll probably just  
leave it as is.  
Thanks, in any case!
