No, it isn't from Pete Millet's site but thanks for reminding me.
I saw several space charge circuits here and there, and this was the simplest one. They were running it with 12VAC on the heaters, but I think I'll try it with DC, same as B+. Seems like the heaters will attract electrons from the cathode even more than the anode does, but I guess that's just part of the whole space charge thing.
