Skip,
The full story on this coil is in an old issue of the TCBA News. The
coil was originally part of a mathched two coil system which I believe
Transtrom used to use in the 20's. Ultimately, they wound up in the
museum in California. Like all old Museum coils i.e. (Kaufmann coil)
The performance of these behemouths is atrocious, especially with their
original components. Both have been upgraded a bit with modern pulse
caps, rotaries etc. and perform better, but the coils are ultra high loss
and are suffering at the hands of the improved tank components. A good
Wysock museum coil will out perform these old monsters by a factor of ten
on power transfer.
