Not a bad idea. They'd last ages too.

They sure would. Their combined internal resistances would see to that;
law of diminishing returns and all that. You really need to establish
what the likely anode current will be.

2-3mA. PP3s can kick out over 100mA.

Amazing what they did with just one tube, though! Got to admire the
resourcefulness that went into such designs.

Oh yes. Resourceful was the name of the game for a long time, now that silicon's cheap few care about efficiency or smart tricks.
