Ayre V3 voltage 110v to 220v

Can Ayre V3 power amp voltage convert from 110v to 220v thru internal jumper without change of transfer or voltage converter? Thanks
Hi :) Do you guys know about voltage conversion on KX-R and MX-R / VX-R ? Also from 110v to 230v / 50hz ?

Thanks, Kjetil
Hi guys,

based on Charles's explanation ordered already Ayre V3 with "right" serial number which is on the way already from US to EU.
Unfortunately, neither Charles non Michael couldn't provide instruction about voltage conversion from 110v to 220v.
I will appreciate if same of you could help me!

Thank you.
Hi everybody,
How about series 7? Can they be switchable to 220v?
