Re: Bach with sparks!
Thanks very much for that Al, much appreciated, but now sparking OK...
Made bigger coil (750 turns)...See my post No6 on this thread.
As I mentioned a variable C in the tank with or without my doorknob cap already there will soon establish tuning errors.
Eventually my spark length will not as big usual as I am using full wave and smoothed DC supply to valves.. It's 4 inches at present without any tuning.
I use DC to avoid any 50 hertz sound that is normally heard with VTTC's. It's good sound that is important not a long spark.
My 2 MOT's run cold so far.
And Dale it's not a singing plasma arc now but on/off spark at the musical notes frequencies.
A midi converter kit I am waiting to receive is polyphonic so hope to hear more that one note.
Thanks again all for help.
