Hi guy's

I ran my coil last night in the foundry at Mass-art.  What a great show.

I would like to point out two things.
1.
Power- 2, 12/60 nst : I was using about 300mf of pfc on them but last night 
I didn't. The amp meter read a steady 22 amps. With the PFC it is usually 
down to 17 or 18. It seemed to me that the coil was making stronger sparks.
Sec coil- 4" x36 1700 turns 24 awg: I used to use a 10"x 36" wound with 
22awg. (It burnt up)   I got 60" to 64" streamers from both coils. So in 
the end the smaller 4" coil is easier to handle and setup and gave the same 
streamer length.
2.
When I was braking down the coil at the end of the night I was zapped by my 
sec coil twice.  It was obviously residual capacitance. Why did this 
happen? When I turn the coil off the stray capacitance should flow to 
ground. Shouldn't it?    I hate getting whacked!

Read you later
