In Fig. 19.9 a more practical load line is shown, though still with
zero quiescent current, on the same curve sheet as Fig. 19.7. The
resistance it represents is 15Ω, and the signal peak is 11 V 0.72 A,
giving an output power per transistor of practically 2 W. The input is
12 χ 0.72/π, = 2.75 W, so with this type of signal the dissipation is
just over the rated 0.7 W which compares with the calculated value
of 0.5875 W for ideal conditions.
