Gotta give credit where credit is due, Andre, even if it is only 1 dB.
The 100 ohm potmeter, shunted by both 100 ohms resistors, provide a
very tiny amount of local cathode feedback.

I didn't say it wasn't *also* a feedback circuit to some
fractional extent. What I said was that the public
idiot Don "Bluster" Pearce mistook the AC humbuster circuit for
solely a feedback circuit

That sounds remarkably unlikely !
