RE: Large Series Gap

Original poster: "Rich & DJ" <rdj@xxxxxxxxxxxx>

This looks something like my gaps , one was .032 between each tube and
runs 7/8 dia tubes ,5 spaces with a 15Kv 30ma NST , .160 total, the
other is 13kv 200ma, 4 or 5 spaces of .050 , 200 to 250 total. I spaced
the tubes with plastic sheets and used quick epoxy to hold them in place
until the glue dried then removed the spacers because even with Teflon
spacers it wanted to jump at the edge of the spacer.

The gaps look way too close to me.  I just space them with a number
of playing cards.  This might help, but I am not sure what the
spacing should be.
