Believe it or not i even posted a video of this pt spiting that big sparks
even remowed and dried from oil affcourse it is from a quality maker! I got
very high voltage out because his primary voltage is designed for 60 V i
applied 240 V!

This is how i did testing ( my asci is bad )

---------- 30 , 35 or more space    -----------
Oh hv side                                        second hvside
It can jump this big spark gap easily!
