In desperation, I once wired the triode section of a 6U8 into an
oscillator circuit that had been designed for one of those 12v space
charge tubes. It worked that one time, anyway.

That reminds me of a fun thing to do when you have too much time on
your hands. Design a tube type oscillator that will work on extremely
low plate voltage. How low can you go? 12 volts is easy. How about
three volts? Or one? Or less?

I'd be interested to hear.
