Has anyone seen anything in print about using a lambda/4 (Quarter
wavelength) stub on the output of an amplifier with a tube. Its a nice
way to bring water, tuning mechanisms into an output circuit, without
looking like a short circuit for the primary frequency. This same stub
is a half wavelength at second harmonic, so it reflects a short right
across the output at F2. This should cause some plate current waveform
modification, depending on where it is located physically with respect
to the plate, i.e., similar to Tyler circuits.
