Bart,

Why the "mains" ground? I have read:
2 or 3 RF Grounds
1 Mains Ground
1 Mains OK if filter is used

You've got it right. The case should be tied to "mains" ground. Then,
240
to the 2 low voltage bushings.

To bring the inner primary at the same potential (RF ground) as the
bottom
of the secondary, tie one side of the hv terminal to RF ground and the
other end to the tank. The hv terminal to RF ground does not need it's
own
ground. RF ground is where the connection is.

Take care,
Bart
