Don Smith Device Project Part 19 B: New Driver testing

Part B …From the one Hv terminal i have the spark in SERIES with L1, then the air cap is parallel with the HV outputs. Freq in that vid is roughly 50khz…im guessing. waiting for my scope to e repaired. This one is only good for viewing. From my signal gen timer chip I have a 470pf cap with resistance of about 100k, so 2 or 3 of those caps in SERIES will put me at 226khz comfortably without being maxed at the dials.. anyway.. BINGO…. building/rising wave form
