I once looked into the more esoteric 12A_7 series of tubes, like the 12AV7 and the 12AY7. Can't recall whether the 12AV7 affords higher Gm and similar or lower Rp vs the 12AT7. Do you know? If and when I get serious about this, I will re-visit the 12AV7 possibility. Beauty of the ECC99 is that it also plugs right into a 12A_7 socket.
