Sweep tubes and G3

Hello All,
I would say that G3 is another electrode to play with. Who knows how many watts it can dissipate before it blows up. Perhaps G3 drive? Perhaps a place to inject feedback?
More grids is equal to more variables = combinations and permutations.
Plan out a few what ifs and hook one up to a curve tracer.
All just for fun!
