I have less knowledge than you presume, but, unlike some, I usually
know to close my mouth when I'm in over my head.

I have been thinking about coming up with a 60Hz L-network problem that
illustrates what goes on when an L-network begins to approach
resonance.

Are you ready for the aforementioned problem?

This has always been the case. There are still some denizens here who
believe that it's absolutely, positively, 100% impossible for a
VHF-rated tube to oscillate at VHF in a g-g HF amplifier.
