Re: grounding question

Hi John,

I'm making a correction in the first paragraph of my post. I 
mentioned the two NST outputs to be connected to each end of the 
primary. That was not quite right. One end to the primary and the 
other end to one end of the cap (then of course, the other end of the 
cap to the primary). I saw the error right when the message was being 
sent, but I couldn't stop it in time.

Take care,
Bart
