If I have a transformer that has a 100v tap, say, and I want to use it in a circuit that needs 40v dc. 100 VAC RMS through rectification = 50v rms ac, x 1.414 = about 71 vdc.
The question is whether to use a parallel resistor, just one, or a voltage divider. I don't know how to look up the load impedance/resistance (control grid to ground?) But if it ws much larger than the dropping resistors, at least the voltage divider equation is a lot simpler.
Is there a way to look up what the dc bias current is, or is this something you have to measure?
