Will, That is a typo. Read the section thoroughly and you will see that you are to use Ibmax in the formula. David KC2JD Gerald, Effective RF load resistance; 2 x (Eb - Ebmin) / Ibo Ibo = Zero signal

Will, those are the classic definitions. Rp = dVa/dIa gm = dIa/dVg mu = dVa/dVg (Va being anode volts, Ia being anode current and Vg being grid volts) and of course, mu = ra.gm. where d is the delta.
