Hello Bart.

Of course I use a RF ground, but only for the base of the secondary at
this time, but that can be easily changed.

Does this mean additionally to RF ground, connecting mains and RF ground
at the transformer? One end of the primary must be mains ground, as there
is noe isolation transformer between mains and HV xformer input.
Or are you referring to the TC itself with "inner primary and secondary"...
I guess so... so I will have to move the cap from one end of the RSG to
the other to get the connections right.

I think we meints the same. Currently the HV connects across the RSG,
one end leading to the cap and then the inner end of the primary, the other
to the tap, so I will move the cap to the "tap" end.

Tanks for your advice
