Re: [TCML] 810 tube coil - update

[David <zipo@xxxxxxxxxxx>]

Hi - Chris, Thanks. In the video the spark was attaching at about 15-16 
inches. I believe a finer and finer level of tuning of the grid circuit 
and tank frequency may yield better efficiency. The Variac is wired for 
140V and I'm turning it up to about 70%. Pegging the meter? :) it's just 
a meter but 2100V and 300ma is getting close to the limit of the tube 
and before I go for the gusto and turn it up more I should make sure the 
tuning is as good as it can get.
