I went to the TRW swap meet on Saturday, and picked up a 866 mercury vapor rectifier. The thing has a 2.5V 5 amp filament. Good thing I had this large transformer in my stash with a 2.1V tap. Needed less than 50V to light it up, and get the emission up to get more than 50mA thru. Tube is rated for 250mA max average.By sticking a 2200uf cap across the the tube, plate to cathode, it turns into a relax oscillator. Tube drop is only 11V. I never had a relax osc, that couldn't bite me. Even though this rectifier was intended for use in power supplies capable of delivering thousands of volts, this circuit is quite harmless, until the glass breaks:
