Is it possible to use a JT instead of the neon tube driver as Don Smith says in his circuit and feeds those coils?
Thanks

Here is something  that might  be helpful

My first tests show that  adding an extra resistor  or pot  makes a better tank

The capacitor that seems to work best  for me  most of the time is .1uF
I have gotten  strong resonance with the second resistor  being as high as 10K

I have not yet tried  the extra resistor  with Gadgitmals tank...... I think it will work......not sure if it will improve it.

   Hi, has anyone tried the cheaper chinese  200 Farad super caps (100,000 cycles)   $11.60 each ?
     
     are the "D" size 350 Farad Maxwell (500,000 cycles) caps any good  ?
     
     thanks.

Freepow:

I have not.  But, Goldmine has those 3,000 F boostcaps for only twice what you would pay for the caps you listed.  About $25.00 US I believe, a much better deal.  Plus, boostcaps can be put in series or parallel in any number where as regular supercaps are limited to 3 I believe.
