Jeff,
        I went and looked at the page(s). I have some questions about
the usage. I saw you using a rotary spark gap, have you ever used these
transformers with static gaps? Also I saw a picture with what I thought
were RF chokes. They were white cylindrical objects in the back of the
box. Are these air core RF chokes? Are these the only chokes you use?
I would be more apt to use powered iron core, or some form which in the
end yields a higher inductance. It seems to me that in order for an air
core RF choke to work, it needs to be a big as a secondary itself. I 
never thought air core chokes provide much protection.

Thanks,
Bob Schumann
