Hi,
I'm currently building the plasma speaker found here
http://teravolt.org/Plasma_Speaker_2.htm
Instructable here
http://www.instructables.com/id/A-reliable-plasma-speaker/step2/Making-the-GDT/
And I had a question about the GDT, Which is driving IRFP250 MOSFETs.
It says that it is 14 turns of 22ga wire,on a 2.5cm ferrite; I was unable to fit that number of turns of a ferrite of that size, and was wondering if 8-9 turns would be acceptable to get it to work? I've attached some pictures.
I don't know all that much about MOSFETs and less about transformers, and wanted to be sure, or at least somewhat sure, that it will work before wiring everything to it, or if I should just try again.
I would ask on the instructable, but the question has already been asked and it appears the author's only response is to fiddle with it. I seem to lack the coordination to wrap one of these in anything under n hour, so I'd rather not do that.
Here's the schematic
If anyone knows enough about this to tell if it would work or knows of any good sites that deal with calculating this for beginners (other than the textbook here) I would greatly appreciate it.
Thanks in advance
