When I look at transmit tube ratings, I see that they're always specified in watts, which makes perfect sense because the grid structure can dissipate only so much heat before all manner of Bad Things will happen. Every amp I've seen measures grid current, and the spec sheets specify currents for "typical" operating conditions for the various tubes. But... How do I convert grid current to grid dissipation? Do I need some kind of grid impedance to do that?
