if you look at pic, i have drawn up a few schematics of my proposed SGTC circuit. i have gathered these schematics from various websites and i need help with which grounding method is correct/best. i plan on using some RF chokes to protect the transformer. im a little confused because different websites show different grounding methods. please review my schematics and post some feedback on which to use or any changes i need. also, where does the strike ring get grounded to? thank you in advance!
