Has anyone tried a preamp-after-inverter topology, ever? I'm thinking the following:
Obviously, the 12AX7 pre-amp tube(s) would be in Class AB1 push-pull mode. This might take some of the smooth pre-amp drive out, causing the amp to sound harsh... I'm unsure.
Note the need for a preamp tube (12AU7 here) still to drive a tone stack.
Thoughts?
Code:
(S) ------------{Va1}----{Vb1}------{EL84}--- -- (speaker) | [+]| ^ ^ | | {12AU7} -{Inverter} (12AX7 1) (12AX7 2) 3||E (OT) | / [-]| v v | | {Tone}-- ------------{Va2}----{Vb2}------{EL84}--- --
