Hi @BassmanPaul - here is a pic of the AC portion of the back panel. Seems like it's possible change the fuse and swap out some internal wiring. Similar to the original poster, I've had a 120v DB659 previously that I emailed Aguilar and they gave clear instructions how to change. Even sent me a link of where to purchase the different fuse.
Those were the good old days when someone from Aguilar actually looks at support emails. Unfortunately I emailed Korg (the support email on the Aguilar website) but havent heard back (yet).
Any input or help would be most welcome.
