Hi, Kerry,
Thank you for the quick reply.
You did mention in the previous post that "
Just don't add the opto relay (CPC1117N) and the 600 ohm resistor (not necessary). It is a normally closed relay that prevents the HV from starting up.
EDIT: Also, the 3K resistor above the relay is not required."
I have gone through every page of this thread, couple of times, and could not find the BOM (or its location) nor the schematic. It would be great if you could provide a pointer.
