There is an old Tesla type diathermy machine in my university, that I
intend to restore some day:

It is exactly as a Tesla coil, with relatively small spiral primary
and secondary coils. The handle at the center moves one in relation
to the other. The structure at the right side is an elaborated
water-cooled spark gap. Inside the cabinet there is a high-voltage
transformer and capacitors.
