I have a homemade simple cap that i hooked in parallel to the output leads of FBT and I get nice big long bright and loud high rep sparks.

is the transformer hooked dir to mains? can you pls explain step by step your whole circuit and include values of voltages amps and capacitance of every component. have you ever tried using an electronic ballast for a driver? you can buy them separately and simply hook EB to mains and to primary of FBT, gives great results similar to what I saw in your video but the FBT must have 11 pins for it to work, dont ask me why but for sum reason it only works well with 11 pin ones.

seems like there is lota amps here I was looking at the schematics where you got this from, your resistor values are a little off from his design but basically the same setup, does the transistor come with diode damper already built in? and did you place a cap to that? so you have two caps one on transistor and one on the transformers output, I am confused as to the value of yours and his? his says 4700mF and .47mF? but you only mention one .56mF? what is the output of your transformer?

Does it have to be that kind of transistor? I have those, and other types and I can't seem to get the other models to do anything >.>

impressive for such a simple circuit. mine only made 1.5in arcs

I noticed as you pull the arc back it remains an arc untill it extinguishes,, how come you dont get sparks before this happens? is this cause of your trans, cap or power supply? cause single transistor drivers or CFL drivers dont behave like that? they make purple arcs when gap is small and as you pull arc becomes zapping sparks from purple to white bluish color.

@ARCSTREAMS This probably depends on the output current from the transformer (related to driver power) and the transformer's self capacitance.

Its possible to use a 2SC1454 transistor in this driver?

@malicious1111 I think it could work, try it and see.
