Hello Thought I'd throw this out again. does anybody or can anybody out there direct or explain to me how to set the bias point on a voltage tube amplifier stage that is configured in local feedback. (on the plate load chart/graph) where the Grid resistor instead of going to ground connects to a node between a resistorRk1 and Rk2 where Rk1 connects to the cathode Rk2 connects to ground. And how this feed back works. Thanx
