David, there's some other changes going on. Prolly one of the more important one is the AA270 schemo seemed to run a 5U4GB rectifier where the AA763 uses a GZ34. There also seems to be a difference in plate voltage on the PI and the size of the coupling cap (0.001 versus 0.01 mfd).

I haven't modded an SF Super back to a BF, but YES, attention of the voicing of the PI is important. Maybe playing with the plate voltage and the coupling cap might revert the SF back to the BF a bit more. And that rectifier.

Good luck!
