Good find! i was looking for a zoomable picture to find correct value odd though no a version schematic.

I can't find a place who sells 82pf 6kv.

Is it an option to place 2x 33pf 6kv and 1x 15pf 6kv parallel?

That is al lot of shipping costs to import from Australia.😐

I tried that in the past to order sample. They charge huge shipping costs with dhl

I even looked on all my parts pcbs if they had one fitted none do (i would of posted one too you if i had one) its certainly a odd value

Thanks for the effort in any case and it's true, I think it's also rare and nowhere for sale. regards

i wonder if its worth taking a risk on going up too 100pf 6kv https://www.ebay.co.uk/itm/283197362...oAAOSw32lY1nQs

Then the voltage divider is no longer correct and it either goes into protection too quickly or it reduces the lamp current.

I'm going to try to place 2 x33pf and 1 x15pf 6kv in parallel, then I'm pretty close at 81pf.

i didnt think of that, your idea is certainly worth a try then
