Hi guys.
Built my first SSG recently and all going well. Been using the TIP2N3055 transistor and all fine. Not getting hot at all. It's only running a bifilar coil.
Just now i changed the transistor over to the MJL21194 and i noticed a few things.
The circuit made a different noise on start up and when the neon flashes when i take off the charge battery.
I noticed it was drawing 3 times as much from the run battery and last but not least, the wheel ran really slow and eventually came to a stop!?
All i did what swap the transistors over. Nothing else. Why is it doing this?
I'm assuming the Base, Emitter and collector are in the same locations as the TIP2N3055 chip?? Or not?
