OK some interesting comments. This set where I got a continuity from the + filament to chassis was purely a battery set. One side showed no continuity but the other side read 0. Then I figured when the pins are plugged in surely there would be just the filament being heated between LT + and chassis. The grid leak resistor of course would return to LT + to stop the grid getting too negative.
I wai have an excellent 1940 book on battery radio. I am also curious as to the price of the Triodes and pentodes for the battery sets. Someone said they are dirt cheap but some say about 20 quid each. Most had 4 or 5 pins. Such radios fascinate me the most as they're Great Depression era.
