Short answer is "No". A mu of 20 is too low to be very useful in GG. As a
swamped grid driven, grounded cathode Class AB2 amplifier with shunt regulated
bias supply, quite possibly, although you would need to look carefully at how
much swamping you need, which may push the drive requirements too high. Or you
could tune and resistance load the grid and neutralise and run AB2 with a shunt
regulated bias supply.
In general, tubes meant for industrial heating have low mu because it gives
less variation of grid current with load, and they are mostly run as self
excited oscillators.

Subject: [Amps] Is this tube anygood for a monoband 80meter GG amp
Good Day,
Well its been awhile since I posted to this list but read the posts. My
weakness is how to determne if this tube is suitable for use as a ssb amp and
does anyone have a tutorial or link on how to use the constant current
characteristic tube charts? That -1000v grid in the specs makes me think it
wont work or be practical but thats why Im asking.
