The normal voltage of the diode can be measured using a multimeter. The specific operation is as follows: (1) Connect the black lead of the multimeter to the positive pole of the battery and the red lead to the drain of the diode (i.e. the negative pole of the tube). ...
Battery Testing Battery Voltage Test To check the open-circuit voltage of your battery, first disconnect the battery cables so that no power is coming in or going out. Set your multimeter to read “DC volts” (for meters without auto ranging, set the scale to 20 volts), and touch the re...

And if you make the cap and drain resistor smallish, you could actually make an AC load to test AC load like for power amps. For dual supplies, the upper half rectifies the fn gen on positive swings and the lower half rectifies on negative swings so you should be able to load ...
