Dear Mr. Atkinson,
Congratulation to your brilliant web site. Could you please publish in your 
archives following notice if possible. Thank you kindly.         Joseph Lovell,

HELP NEEDED : Charles Rakes wrote the article about a Solid-State DC driven 
TC (common,"upright" TC) in Popular Electronics (Farmingdale), 1999, November 
iss., pg. 31-40. The circuit is built around a 555 oscillator; a pair of 
IRF9130 (100V/11A) power Mosfets; a gaggle of diodes (IN4007) and a pair of car 
ignition coils. Powered by 25V/2A transformer or by battery. I wonder if anybody 
tried this relatively simple design. I like bipolar TC (no need for RF 
grounding) and I would  like to modify this design  for use with BIPOLAR TC, but I am 
not sure if my modification is correct one. Also, I want to use IRF9540N   
(100V/23A) Mosfets instead IRF9130. I wonder if somebody can help me. I shall 
post him both circuits.       jozefau@xxxxxxx
