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.
