Moving to France

Contact your manufacturer for precise info for each device. (minorl is correct.)
Many power supplies have transformer primaries which can be switched from parallel to series by moving a few wires, and changing the fuse and IEC power wire (they hesitate to reveal this to reduce grey market imports).Have a great time in France and the food is wonderful! (Escargot is only an appetizer). Learn the language.

You don't mention how long you're planning to live there, since you want to keep your components I assume it's a temporary move. Step down transformer would be the easiest route. If you're taking a turntable it might not run correct as the 50hz would make the motor turn slightly slower. There are frequency converters but they're pricey.

No no Miller carbon. He said France, not Seattle. 

Once there, try to check out some restaurants and bakeries run by American ex-pats. They’re off the beaten track but are making a huge splash in the culinary world. I saw it on some cooking channel and can’t, for the life of me, remember which one, or I’d send you a link.

You’re in the wine capital of the world, and for that, I’m jealous. 🍷🍷🍷

All the best,
