changing from 220v to 120v

There are a pair of Bryston monoblocks I am interested in that are 220v. The dealer says he can change them to 120v before shipping. I know next to nothing about electricity. Is the conversion easy to do correctly and well? Or migth there be non-trivial issues involved?

thanks for your thoughts.

I know nothing about the internals of Bryston, but it's often just spades on a terminal block.  Takes a phillips head screwdriver and voila. :)

Depending on the gear, yes. With linear power supplies we often see transformers that are manufactured as dual voltage units. These transformers use two primary coils, and depending on whether the primaries are connected in series or in parallel to each other they work with 220 or 110.

It’s a common cost-saving technique.

Best,

Erik
