Oh, OK. I thought you meant the "internal feedback"
concept that's going around on rec.audio.tubes.

So, why must a triode design inherently have more local
feedback than any other?

I was wondering about that term "local feedback" too. It
sounds like
one of those terms coined by the same folks who talk about
LDC and
SDC. Is it some hip name for not bypassing the cathode
resistor?

Not bypassing the cathode resistor is one way to get local
feedback. Other techniques include a resistor from the plate
to the grid usually with a blocking capacitor, and cathode
windings on the output transformer.
