 MR> Hello Richard,
 MR> Richard Hull advocates using a single bypass capacitor (or
 MR> multiple in series as needed) between the two HV leads of the
 MR> transformer.  Other components remain the same.  He does not ground 
 MR> the center point as you do. Any advantages?  It seems to me your 
 MR> method is probably more advisable since it would better trap RF 
 MR> kickback if one of the RF chokes shorts out (arcs to the ferrite 
 MR> core, like one of mine did!). 

This really depends on the type of step-up configuration used. I wire
both ways: with the bypass ungrounded where the HV secondary is not
center tapped; and grounded when using neons or other center tap grnded
step-up xfmrs.

 MR> Hope your new house details settle out soon.  

HA! I am sitting in my new office right now! Still a lot of unpacking
and wiring to do!!!!

 MR> Would like to share some comments on primaries/coupling some 
 MR> time in the future.

This would be my pleasure.
