plate resistance || plate load resistance || following grid resistance
----------------------------------------------------------------------
(1 / transconductance) + cathode resistance
A sample circuit image
is available to show the resistances used.
NOTES:
This equation works best if you have a cathode bypass cap
and use 0 ohms (for AC purposes) for the cathode resistor.
Values may be any standard form (68400 or 68.4K, 1M or 1000000, etc.)
Check the "Use comma for decimal point" box if you use a comma to designate
a decimal point (i.e., opposite the way it's done in the USA).
