Gated Pulse Frequency Generator Schematic

ok.... finally .... its not the adjustment that doesnt work its the sim.with the values posted and running 5khz am into it  if u manually change the pots value it works but with the 5khz it doesnt work under 90kohms.and i cant get a square wave into it to work at all.

Newguy, is much simpler to use a 555 timer and an opamp like 741, so you can vary from 0 up to 100% dutycycle without changing the frequency. Please Don't think that this circuit for the gate is absolutely necessary or the only way to make the gate to put the thing to work cause its not.

Of course is better than the opamp, for higher frequencies, maybe,,,

The important thing is to match the impedance so you can apply maximum voltage to the water restricting the amps.

ok but its not changing the frequency the only thing its doing ..well i dare say the only thing but ......  wat its not doing is changing the frequency.What its doing is timing how often the frequency goes thru.(duty cycle of the frequency)Im very currious how the cell driver circuit effects the pulse from this gated signal but I would almost bet it just amplifies it so the the primary dont burn up the circut...  but i really cant wait to see a waveform from this circut to me it looks just like his drawing... thing is his drawing looks like a regular square wave untill youve played with this circuit for some reason you have to usually slide the pot a lil bit to get the sim to start sometimes  ....

try this circuit....works better in the sim

 Thanks Ali, i think i got overexcited for a minute i found an error on connection K and i dont like connection K lol.   The waveform has changed to something regular on the sim thru a transformer so Im kinda depressed rite now lol.

ok my hopes are back up again....i just picked the first coponents i found to check it again but now the waveform remains the same thru a transformor

Hi Newguy
I have question to You . Is Q4 connected corect in this sim?

Just want to let everyone know that this circuit doesn't work. I built it today and couldn't get anything at the at the output, not sure what the issue is with this circuit.
