There is no max grid-I rating. The max rated grid dissipation is 20w,
but several experimenters have found this to be somewhat conservative
-- probably because the grid is made from Mo, which melts at 2617ºC.
Figuring grid P --- According to "Care and Feeding ... ... ..." ,
grid-dissipation is approx. the indicated DC grid current multiplied by
the RMS grid to cathode potential.
