Coilers,

Has anyone tried using a bipolar transistor (Darlington array, not FET) to 
make a small or medium air-core tesla coil?  I have done the flyback thing, 
and I just ordered some big 1000V, 75A Darlington transistors (Toshiba)in 
hopes of replacing my 2811A (65W dissipation for each tube) vacuum tubes.  
This would be a big improvement since it would be self-tuning, no filament 
tranny, and more power.  I have heard that Darlington arrays have a 
different phase shift than a single transistor, but I'm not sure why other 
people have said that Darling's are better, other than because of much 
higher gain.

Any advice/ideas?
Craig
