Well, that's where I was going when I asked "what bizarre failure causes me
to lose both of my completely independent transceivers, and my transponder,
but leaves me fully confident
of the continued flawless operation of my other avionics?" An electrical
failure will affect all of your installed avionics, not just the
transceivers and transponder.

What additional installed avionics do most of us have? Other than the audio panel,
everything connected to my electrical system is a light (well except for pitot heat).
