45 volts peak (driver stage feeding output tube) across 250k grid resistor is .18ma
.18ma flowing across .02 ohms gives a .0000036 volt drop.
If we factor in the current needed to drive the Miller capacitance of the output tube the current will go up.
Assuming 3ma. and the voltage drop is .00006 volts.
