Well, having looked at some Neumann and AKG tube mic power supply schems, I notice that they all use a row of resistors connected to a rotary switch but if I wanted to use a pot instead of all the resistors, whats the best way to calculate the value?
Would it have to be the same as the combined resistance of the individual
fixed resistors in the chain?
Comes out at a really odd value if it's say 8x 5.6k.
Sorry if this is a really dumb question.
Thanks
