That isn't true Rich.
Removing the current limiting allows the operator to overdissipate
the grid, and that is the single most common cause of failure in
MOX cathode amplifiers.
A resistor is not even near as good as a fuse, and a fuse is
actually too slow and unreliable to protect most control grids.
Removing fast electronic protection and using an unreliable and
slow acting resistor as a "fuse" is a simple answer, but very bad
advice.
