Hey Finn,

On the 2nd link, there's a pic of the coil with the copper toroid. Which coil is this? The Museum Coil, the Ambassador? Kind of curious on the copper toroid. Is this a copper plating? If so, how is it holding up?

That`s the Museum coil, which has now been operating for  6 years.

The copper toroid is spun from 1.5mm or 60thou copper sheet, on the same tooling as the alluminium ones I had made as a group effort long ago.

It gets quite dull after a year`s operating, but it polishes easily and this is a good reason for a yearly touchup.

Cheers, Finn Hammer
