I am sure this can't hurt...

If you could dig up those posts of mine from last year, they will explain in
detail, but I noticed that the arcing to the grid coil only happened when
the polarity of the grid coil was a certain way. I also found the direction
that the coils were wound made a difference. There is also certain settings
on the staccato control that seem to cause or promote flashover. The ring
will protect your grid coil in these cases.
