N-set, actually, I have seen a stacked-L schematic like you posted, with stacked caps layered over and R at earth for the tank, and I am on record as saying it is very elegant.  So, sorry to be such a skeptic, but I learned a long time ago that the only way to know for sure what happens with a real circuit this complex is to build it and run it how you want to run it.  I was thinking the cathode diode is +/- a "follower" (what I call "deniable feedback"...), and I would not bet on alternate versions.  In fact, I spoke with a guy not long after he heard that amp and he said it was not special, at least under the circumstances, which the designers, after all, controlled, and he also said they seemed happy with it. Well, I can certainly live with "not special" if it simply gets the job done for me; but who knows?  You say you are OK with the mains tranny, and I am OK if you are OK with special winding it, and I hope you are also saying it will be cheap!

But never mind all this; you want to stack just two stages (?) for headphones only, and your idea appears to "work" into an actual capacitor!  You can zap a long arc off an EL34!  Now, if your circuit runs predictably and quietly into a real-world reactive load, with a real ground tail, you're home free!


Best regards,
