Nick,

with 100K resistors at 24V they should pull (I=U/R) 0.24mA and thus dissipate (P=U*I) 5.76mW, so any 100K value will do.
Even 10K resistors can do the job (2.4mA / 57.6mW).

   Ok, thanks for the info. I do have a small bag full of new 10k resistors. I'll also recheck your posts. I think that it's important to check on the device, to see just where the power is being lost, and to help figure out what to do about it.
   Good to know that you're working along with Verpies on the modified PLL.

Well, you have it next to the grenade coil and it is main part of the system anyway...

...but who will insure his scopes, FG & SA ?

[verpies]

It's interesting what Verpies mentioned about your having better output on the yoke, as compared to the output on the grenade coil. As the number of turns on the 168t coil, compared to the 3t or 28t coil, as well as the additional rectifier circuit attached, the output should be the other way around.

It is more about the coupling coefficient (k) between windings than anything else.
You can measure this coefficient by shorting one winding and measure the ratio of how many times the inductance of the other winding has decreased.  Ideally it should decrease to zero.

Here's a quick video of the final prototype up and running,  the scope only shows the complementary push pull outputs of the SG3525. 

What is your method of converting the AC sine waves generated by the LC circuit to square waves, without distorting their phase relationship (the 74HC4046 phase comparator expects square waves that are in phase when the LC circuit is in resonance) ?
I have found that if I use a voltage comparator with a hysteresis to do that, then the hysteresis introduces a phase delay....and if the hysteresis below 0V is different than the hysteresis above 0V, then the output becomes even worse, namely it stops being a square wave !

Without the hysteresis, the noise immunity of the sine to square conversion suffers dramatically !

hi all,
i have written yesterday a message , some attachements with it . I still have "Note: this post will not display until it's been approved by a moderator."  any help from moderator?
thinking that attachements may be the reason, request again assistance from  more experienced experimenters:
I'm driving a flyback transformer with 555  pwm/irf840. output of the flyback is feeded to a toroid via sparkgap and from the toroid just lighting one of 9w led bulb. amp reading (drwawing from battery ) is fluctuating -so i make assumptions for what is consummed with voltmeter across one 0.16ohm resistor in series with negative feed from batt. In normal operation reading is 130-160mv(so @1 amp) , but if I connect a gruonding cable to mosfet drain, voltmeter shows 30-50mv, abt 3-4 times lower. no changes noticed on light bulb, same noice on flyback and sparkgap appear to fire at the same rate.
I don't say is bad but why is happening? 555 pwm is powered from separate batt/supply. if I touch grounding cable to any other place than negative terminals(incl batt negative ) , comsumption is increasing.
any ideeas?
thanks/rgds
