[TCML] Fixing up an old coil -- tune-up suggestions

[Barton B. Anderson]

Hi Jason,

Your previous measurement of 393 kHz would indicate 14 gauge wire at 
about 510 turns. I used 16 gauge originally which allows for more turns 
resulting in a lower frequency. That changes the cap size required. 
You'll want about 7 bottles which will tune in likely in the last turn 
of your coil. The 14 gauge makes more sense with the original brine 
bottle caps as a smaller capacitance would have been needed.

I do have a bottle cap calculator which may be handy.

Bottle cap capacitance changes with volume, area, solution, etc.. The 
example I show in the bottle cap calculator will show a capacitance very 
near the corona sized bottles.

Oh, as far as verifying the output current, yes I meant just to read the 
label.

Take care,
Bart
