Plotting Push Pull Comosite Plate Curves

[nickb]

For anyone who might be interested, here a a SPICE simulation that will plot composite push-pull plate curves. Note, in order to have a single load line, the plate currents are plotted relative to the bias current. In other words, to get the actual plate current add the bias to it.

Typical results:
