Greetings everyone. First of all I didn't see an area to introduce yourself (forgive me if I missed it). My name is Michael, and I've worked on antique radios for quite some time, but am moving to the area of amplifiers.
For my question, I'm using the schematic below as an example. The B+ starts out at 360 volts. As you go down the line, there is a 10K resistor, and it shows the voltage drops to 320. Then a 22K and we're at 280 volts and so on. What I can't figure out is how does it come out to those voltages? When I try to calculate the voltage drops, I get completely different figures, and that's accounting for the plate and cathode resistors.
Or to turn he question around, if I was designing an amp, how would I calculate what resistors I would need in the B+ to get to the plate voltage I need?
