How about that, my Philco 3118 and Rogers Ten-12 have, or did have class AB power output stages? The latter set had it rewired into a garden variety push-pull pentode amp rather then "triode connected" as it would have been originally, I want to put it back the other way. I believe that the Philco 16 and 116s had this, the audio interstage transformer is a step down transformer rather then a step up, and that infamous bleeder resistor connected between the B+ and ground.
