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.
