Makes sense, Brett. I was trying to work it through using diodes at the
"bottom" of the grid-leak resistor, and there didn't seem to be a simple
solution that way. But since I'm using the grid-leak resistor also as
the RF choke (typical old-buzzard practice), so I'd have to add an RF
choke. May

The grid gets its bias the normal grid leak way.
At the grid side of the resistor, a diode is installed between the
bias supply and the grid, in the direction that allows it to pass
bias, but if the grid leak exceeds the fixed bias, it is reverse
biased.
That's cathode towards the bias supply I th
