6080 audio amp?

Hi, Vacuumlanders.
Just a speculation but has anyone built a P-P audio ampliifier with
the 6080 (6AS7) tube? (twin power triodes used as the series element
in voltage regulators)
OK, why would you want to?... it's low voltage, high current, high
bias, likely difficult to drive, you don't need to since there are
plenty of better alternatives, etc...
My answer: I have several 6080's (mostly NOS); getting bored with
designing for 6V6, 6L6, EL84, EL34, etc (well, not really!); you get P-
P in one envelope; I have a couple of spare universal replacement
OPT's (the Hammond 125E) so a choice of plate-to-plate impedances from
3000 ohm up (low enough?) is easily obtained; two O/P tubes for
stereo; and, finally, the 6080 sort of looks nice!
So, any opinions on this?... including don't bother! g
Cheers,
Roger
I bought a couple of 6AS7's but did not yet build an amp with them. I
think it would be cool to have a push-pull tube amp in one envelope.
