Default Anyone came across AirTight ATM-2 schematic?

Probably one of the best KT88 integrated Push-Pull amplifiers , what's so special about the circuit?
It uses 2x ecc83 ,2 x ecc82 ,2 x 12BH7A , Tamura OPT's
I have built few incarnations of KT88 Push-Pull transformer interstage coupled , with input transformer splitting , used different input tubes , not bad Lundahl transformers and final result was resulting in sound much worse than simple PP El34 , srpp ecc83 , ecc81 LTP.
I wonder if Transformer coupling is any good?

Why not show your schematic on the 'sound much worse' amplifier? You will probably get some advise.

I don't do transformer coupling because I haven't yet felt the need to.
