I agree with Steve on this one.  It is very important to safety bond metallic
components, _particularly_on_the_LV_(control)_side to a known reference
(i.e. safety AC ground).  I would also put a line filter on the primary side
of a MOT or NST and a RFI choke (low impedance to 60Hz, high 
impedance to RF) on the ground between the case of the NST and a 
Terry filter on the
HV side.

Grounding/bonding is a critical exercise to industrial equipment; people have
DIED by having defective safety ground bonds.
