Breaktru thanks for the link for parts, already reviewed 16 pages on Ebay  exhausting!!!!! Hopefully my last post will help others. Trust me to all who have a working ohmmeter, which I don't have in hand, but you just need to use the existing switch to restore jumper removed which I believe was not a resistor originally but just a jumper,anyone have the removed SMD to check it, can't be too safe, no smoking circuits, don't need to remove the 9.99M resistor just short across it when using ohms, remove short when using volts, and don't use the 10K resistor across the Ra = no scaling= original 200mv range.

This is why for safety sake of the meter I would of tried the voltage divider totally external to inputs, for accuracy I can see eliminating any possible drops by using New Ra across existing Ra, but electrically I believe that Rb could of been external or in series with the correct input lead, with no difference to accuracy, come on it in the Meg ohm range no little drop or difference in current can be noticed due to some added wire length, the dropping resistor does matter.

Finally made my first try, basic test model... only took 11 months lol! I had forgotten all about making this, all of my pieces were put away and collecting dust. The reason I wanted to make this was so I could make nr-r-nr clapton wire to re-wick coils from my tanks.

So I finally got around to digging out all my kit and made up this basic model in about 20 mins. Going to be testing it over the next week before making my finished model with the panel meter.







The button is just for charging the caps, like I said I am keeping it simple to start!

With the majority of the comments on this thread, the General consensus is around 320-340uf
Since I'm only gonna hit 75-90 or so volts  ,could I swap out cap on camera pcb with a 200V 330uf
Cap RATHER than having to add more to the smaller oem ones? Thx for input....
Great job breakthru :thankyou: ;cheers;

Yes hotamele. 200V 330uf should work fine by itself.
and thanks.

I have this Spark-O-Matic thing down pretty good, you have to be careful fixing one of those brass alligator clip vertically
