And so, in a cloud of grey smoke, the graceless Patrick slithers
away.

Porky took not a blind bit of notice, BTW, and appears to have
fallen into the clutches of the half-baked hack calling himself
lbrty4us, who had the unmitigated audacity to suggest that you are a
poser "in the whole area of basic tube technology". If you nip over
to AGA you will find he writes such drivel that even you should be
able to give him a proper pounding, if you stick to RDH and don't
get carried away with more foolishness. Don't just paste him
willy-nilly though because he is right about some things.

Perhaps you could tell Porky about typical triode loading, and
direct him to datasheets where he can find typical operating
conditions and values for Ra and gm, so he can set up his daft AX7
cathodyne.

Just wondering if it's direct coupled, and if there is nfb to the
cathode of the preceding other half. Doesn't appear to know ohm's
law yet, could be right up your street.

cheers, Ian
