  Jim -

  Tuve, et al did build and test a 5 MV TC in 1930. A drawing is shown in
the Tesla Coil Construction Guide. Also shown are some calculations on how
they determined the power gain.

  The Guide also shows a test method to measure the TC secondary voltage of
a small TC using a remote pickup probe. I made some tests with this setup
using a small TC but the results were inconclusive.
