Default B&K 747 tube tester

Hello

I just bought a B&K 747 tube tester. The electrical network in my country uses 220 V, so I need a 220/110 V stepdown transformer, but I don't know much power I need.
I think a 110 VA transformer should be more than enough, but I am not sure. Can anyone help ?

Dear Tigro

I faced the same problem when I got mine. If you open it and see the transformer inside, you will notice that a 100W stepdown transformer is more than enough.
