Thanks. Any info guys?

Please understand I am in NO way casting aspersions on the master.
But I do realize that he didn't have the luxury of the kind of gear
we're fortunate enough to have access to. I think you can see why the
questions I asked are important in the light of what I said recently.
I wanted as much background as possible so I could nip in the bud any
erroneous thinking on my part. I was keenly interested to know what
his thinking on the characteristics of spark discharges was since
it appears to matter a great deal.
Thanks for the info you provided.
