Who can repair Sonic frontiers preamps?

I will be pleased to buy one second preamp, and I´m thinking on the Sonice frontiers SFL-2. As I´m in Europe, I want, if it´s posible , to upgrade to a 220V, who can make this change?.Thanks
Another question is , if no body can make this change, may I run it with a simple transformer 220V to 110V?
Yes, you can use a converter. For modification contact Chris Johnson at The Parts Connexion.
Narrod is correct. Chris Johnson of Parts Connexion is a former principal of Sonic Frontiers and will be able to help you.
