" The capacitors are .1mf each, for a total of 12, in series."
MG> I'm curious Chris, what kind of capacitors are they?
" The secondary is about 470 turns of 26 gauge magnet wire on
a 24" long 3" diameter form."
MG> Chris,
MG> You don't state how long the actual winding is, 470 turns of #26
MG> closewound would only be about 8 to 9" in length and if wound this way
MG> would tune at around 900 Khz to 1 Mhz.** If your using the full 24" or
MG> anything close to it by space winding the secondary, it most likely
MG> is resonant MUCH HIGHER in frequency and VERY LOW in inductance.
MG> I believe the coil is WAY OUT of tune, and depending on your actual
MG> secondary construction, may not be useable. The sparking at the safety
MG> gaps is occurring because the out of tune condition is not allowing
MG> the secondary to "absorb" energy from the primary and a standing wave
MG> is being set up in the primary circuit. This could cause transformer
MG> and/or capacitor failure.
MG> ** Depending on the terminal
We've spent all this time
and we're just disappointed...any ideas?
chris, evan and andrew dunagan >>
MG> Don't be too disappointed, your learning!!
