You should use 6.6 Kohm primary "iron" that has PLENTY of magnetic headroom. Core saturation sounds terrible. :>((
Make darned sure you don't exceed 5881 dissipation limits.
The Cit. 5 is a superior implementation of Mullard style circuitry. Save 12BY7s for already existing builds. I'll post a 6922 cascode for the voltage amplifier later, from home. In keeping with the high gm theme, use an ECC99 as the LTP phase splitter. A 10M45S CCS as the LTP tail load is another refinement. Yet another refinement is regulated O/P tube g2 B+. FWIW, Jim McShane shoehorns a choke into Cit. 5s, to improve O/P tube g2 B+ regulation. Space is too tight for active regulation circuitry to fit. Be sure to allow yourself maneuver room.
