The obvious answer would be to go Class D as most of those are switchable but to change the answer to your question slightly have you given thought to the economics? Using the U.K. as a for instance if you buy an amp in the US less than six months before you move you will have to pay VAT on arrival in the U.K. (20%). Of course anything you buy in Europe will have VAT on it as well.
As it’s a trivial job to switch any given amp from 110 to 240 or vice versa have you thought of ordering your preferred tube amp in the US, speccing it 240V and having it delivered suitably in advance of your trip? If you prefer US models they will be much cheaper bought here.
As I’m actually relocating back to the U.K. now after 24 years in the US I’m working through all of this now having all of the active components in my system switched. It’s a pain to have to send them back to the manufacturers but on the whole not expensive for the work of changing, and also good to have them all looked over. For the EU sourced pieces I’ll wait till we are in Europe to do the work.
