This project started after a trip to the Dayton, OH hamfest.
I picked up some tubes and some large high voltage mica caps for a good price, and started building.
I found that the 811A was easier to get working than the 572B
(Even though they are supposed to be interchangable???)
These tubes get hot!
Some sparks, but not too impressive.
