An absence of NFB **DOES NOT** make any ampliifer
'inherently stable'. Such an
idea is pure horse manure.


But trying to introduce more than say 16dB of NFB in a
PP tube amp introduced stability problems which few
homebrew builders have either the skill or equipment to
solve.
Compared with this, SET is pretty amicable. That was
my point.

Yes, getting rid of NFB dumbs down amplifier design to the point where naive
dilettantes might be more likely to construct an amplifier that does not
summarily incinerate itself when first turned on.
