very unusual teddy, what looks like 2 high voltage outputs is actually one high voltage output and the other the return , and the inputs well the neg is normally allso the return but i see its not , just different . i have a high voltage flyback transformer and it has a hv out and return both at the top like your coil has them both at the front, keep up the good work tedy lets see ya driver circuit for it , is it the same as the ones i use they are easyer to make toIgnition coil driver circuits and experiments

oh by the way if it takes to long to read all my posts . when exsperimenting with my high voltage output flyback transformer some time back, useing the same driver circuit , a wire come off a pot and the whole circuit went into resonance , acording to what i was told , the flyback would of went into resonance with the mosfet, resulting in super longer arcs , allso at the time i was allso runing the hv outputs through a modified high voltage polarity indicater , i think, anyhow if ya get it right youll be suprized at how far the arcs would go , and the battery i was useing, i think i was useing the high power 12 volts lead acid cell rechargeble battery for it
hi! you have the schematics of this?
can you send at my email? [email protected]
THANK YOU MASTER!!!

THANK YOU MASTER!!!
i see you use a mosfet instead of the 2n3055 npn power transistor , and if ya did use the 2n3o55 tranny , then you will have less chance of looseing that transistor as its not static sensitive like the mosfets are and will last longer . for the mosfet well you will need an mov from drain to source for protection

audio guru ive lernt that from surfing the net that movs are handy for mosfet protection , i was looseing mosfets in the circuit and so when i put in an mov ive never lost a mosfet since not bad hey , and even if they was suposed to be protected in circuit then the mov would provide the extra protection

With kilo-volts flying around in arcs, more protection provided by a MOV is good to have.
mosfets are very dear here , and the npn power trannys are cheaper and i can use the 2n3058 to besides the 2n3055 for the ignition coil driver , the 2n3058 can handle more voltage than the 2n3055 but then i use 12 volts lead acid cell batteries so im satisfied with the great arcs i get from 12 volts , i have no need for any more voltage input than i can allready get

"Any electronic device operating at a potential above 10,000 volts should be considered as a possible source of x-radiation even though it was not designed for that purpose. Devices are not considered hazardous when operated at voltages below 10,000 volts because the inherent shielding, such as is provided by the device walls, is generally sufficient for adequate attenuation of the x-rays. Even at somewhat higher voltages, this inherent shielding may be sufficient to reduce the radiation to an acceptable level."

Cooperman,
I do not think the "High Voltage" members need to worry much, unless they are making their own vacuum tubes. According to the 4 requirements in your link for a device to be emitting radiation, requirement #4 is "Low gas pressure between cathode and anode, i.e., a moderately good vacuum."
