For whatever it's worth, my SB-220 will match an indicated SWR of well over
3:1 on 80 meters (running my 80-CW array on 75 phone) with normal grid
current. In other words, as long as the plate loading is capable of
achieving a match, loading heavily enough causes the grid current to drop
down where it should, and adding a little more loading gives some safety
margin. I can see where this would be important for tubes with fragile
grids, but the message is that excessive grid current isn't the unavoidable
accompaniment to high-SWR loads, if the Pi network can match them.
