Presumably the usual resistive suppressor in series with the anode only
works to dampen the vhf resonance when the other end of the suppressor
has reasonably low Z path to ground.

Is there a case for adding a shunt suppressor load to cope with when
there is a high Z anode load at vhf - a state where the voltage gain
will be highest? Mental arithmetic makes me think it would have to be a
C/L/C high pass filter so as not to cook things on 10m.
