hello, 
 
[quote name='dood' post='210301' date='Jun 1 2008, 12:01 AM']So, have you bought a 110v Ampeg from the US and want to switch it to your native power? *winks*[/quote] 
 
No, someone bought this amp broken and wants to have it fixed. 
It's not a matter of voltage, rather transistors in power amp. 
 
EDIT: 
I got schematics for Ampeg SVT6 Pro. Please find them attached. 
 
Greetings, 
Adam
