Mixed Bias designs, anybody?
Anybody doing "mixed bias" designs out there?
Note that I don't mean selectable designs, e.g. a cathode OR a fixed bias selectable by switch. I mean mixed biasing, as in a class AB1 amplifier output section using a pair of EL84 and featuring cathode cap/resistor AND a B- supply, each sharing a portion of the function of setting the tubes' operating point.
Just curious. I'm cooking up something in the Utility Muffin Research Lab.
