Solid state Bedini charger from John Peters

Ok, I have tried with 12v source and it works.  But it charges faster with higher voltage (I use ~19v adapter)
I removed everything else from the project board I'm working with and check various points for shorts.  It all seems to be wired as shown in the attached diagram.

I tried using a 200v 440uf Cap in place of the charging battery to get an idea of how large the spikes are.  I had to add a 2nd one in series to get the total ~250v.  The size of the resistor I use determines the time it takes to charge the caps.  ~440 ohms was what I found to be a sweet spot. 
The input was measured at ~410ma x 19.1v = 7.831watts
Time to charge the caps to 250v was ~10seconds
1 to 2 seconds after charging begins the neon lights up due to resistance of the caps as they fill I'm guessing.  Unfortunately I cannot hook up the battery at the same time as the whole spike goes to that instead of the caps
I may try adding it in with a resistor but I think the neon will just take it as before instead :/

Hi Niofox interesting about that circuit. Now I am using Groungloop's circuit. It consumes more amps but charges faster.
Thanks

Hi Guruji, can you give link or diagram?

@niofox;

I think he means the one with link starting here:

If you want to boost the charge voltage, what I would
do is extend the sense winding with more turns
leaving the base connection where it's at then
rectify.

You can't use wall adapters above their listing
current. Plus battery charging is somewhat unstable.
Batteries shouldn't heat up while outgassing
extensively, so I would not go to ever higher
charge power without limiting the voltage.
