Anyone wanting to use tubes may want to also check out Svetlana. They
are the premier ham transmitting tube company, Russian. Their products
are relatively inexpensive compared to Eimac. I would think a multiple
811 setup would make a pretty cost-effective tube driven coil. But
still 4-1000 broadcast pulls can handle 5-6kV. Rob.
