RE: bias setting

MA and V in this case are basically the same. In either case, you're measuring voltage across a small cathode resistor. .35-.5 volts over a 10 ohm cathode resistor means 35-50 ma (.35ma is almost 0). Likely, your other amp has a greater range of negative voltage in its adjustment. If you can find a schematic for your amplifier, you can ammend its range for your particular tubes.
