Thanks Ali, I guess the source was lost in a quote of a quote of a quote - 
Thanks for the new info - I'm sure lots of people will find the acceleration parts especially interesting...
I'm still waiting on parts before embarking into that area...

The A22 on fig 4.....  what could that possibly be?

Thats a 5 volt regulator

Still no luck with the 5VIC. I've been trying to get high voltages out of it and have only been able to get around 40v at the output with the cell disconnected. With the cell connected Ive only be able to get around 8v. Anybody else with a similar 5VIC been able to get the need HV?

Not sure yet but have you ever tuned Bob Boyces circuits? Fig 12 has selector switches for each frequency ...  just a thawt.

Tony, have you tried to find the resonance frequency for your coil set up?
Your scanning circuit may not be in the proper range for your coils.

Yea I've tried all frequency ranges, I even replaced the 100nF cap between pins 6 & 7 of the 4046 to a 10nF so I could get higher frequency ranges.

its actually a resonate circuit when you tune it like this or a form of amplitude modulation.Ive added fig 3,4,6,12 with the 8XA cell driver part.... check out the increase in amplitude on the frequency generator im try in to fix 3 and 4 now if you wanna have a go at it..... i dont know if the values on 3 and 4 are rite, Im searching now where those connections go  ... the K10,K11,K3,K3.The sim shows it better if you unhook the scope leads and watch as you one at a time to each of the frequencies.I dont have my cell yet... old got trashed but.... i think the capacitor will act like a filter and without the frequencies adding like that in the sim on the FG then the resonace kills out rite.... just a thawt.
