Hi Bert, Group,
     I had always wanted a good horizontal coil. So I made this one big 
enough to work well. The concentric primary gives good coupling and you get 
a good pulse on the tickler winding(grid feedback). I tuned for a good 
negative pulse on the grid of the toob. I ended up with 15 T. on the 
tickler. At the same, you tune the grid leak resistor for the current in 
the toob. The PS is a MOT with the shunts knocked out. This made a big 
difference in performance. Prolly 3 to 4 inches greater. I use 4 MOT caps 
in parallel for the doubler. Also, I use 16 each

      Terry, how do I get pictures on the list? I have a few pictures of 
all this mess in operation. I also have some WMA files of the coil in 
operation. Contact me off list and I'll email it to you.
