Ken,
In the 70's my business contracted to build dozens of
3CX3000F7 HF amps. We build a collet to ground the grid ring
to the chassis.
None of them ever showed any sign of instability and none of
them used any form of suppressor.
We even built some for pulse applications using custom
selected tubes running at 12kV, and they were perfectly
stable also.
