Re: [TCML] Pictures of my Tesla Coil

[Ed Phillips <evp@xxxxxxxxxxx>]

These coils can handle rather high power with no problems as long as you 
keep racing sparks away. About 5% more primary inductance above the 
resonant tune point is good to help with this especially when power is 
increased. The other item is to keep coupling high but not so high that 
racing sparks occur. Also, if high powers are used (say greater than 
100mA transformer), you have to keep an eye on the lower secondary 
windings as they can begin to burn. I run a very similar coil but I had 
to lower coupling due to the bottom sec turn burning (no racing sparks, 
just burning). The transformer is a 12/60 NST with 1/2 the shunts 
removed. Since I fixed that I've done some rather long continuous runs 
on the coil (20 to 30 minute runs which is extreme for a coil, but it 
just keeps on going).

Here's some photo's of that coil for reference.

Take care,

   What's the power input to that coil?  With all those streamers 
floating around the garage have you had any disasters?
