Paul, below is the Axiom. I must say I've never heard it nor know anything
about the objectives behind the amp. I've just found the topology very elegant
and appealing. As far as I understand, the diodes
are used for biasing rather than resistors because the signal will see several times
less of the cathode feedback (low dynamical R of a diode), but at a price of
the added distortion due to the diode non-linearity. But anyway, most of the biasing V's
are produced on the loading chokes DCR's. Very elegant! But the driving tubes have to
be quite stable if I'm not mistaken.
Encouraging comments on EL34...what I've heard were mostly bitchings.
Cheers,
