"Wild amp !"
The characteristics of the 6Y6 pretty well dictated the "route" taken.
The B+ rail was going to be "short". I wanted, circumstances permitting, to follow the KISS precept. The CCS loaded 6922 section DC coupled to "concertina" phase splitter seemed obvious. However, triodes can't swing close to the B+ rail, but FETs can. Enter the SS phase splitter.
Elements that work in a modest B+ rail environment were selected. An added bonus is that all the small signal devices exhibit high transconductance, which provides resistance to slew limiting induced by the GNFB HF error correction signal.
