That's about right. PSE cuts the turns by root2/2 v. the single tube loading. The PP has exactly twice as many, though each half has exactly as many turns on each side of CT as the PSE. It is quite easy enough to drop leakage L, and winding capacitance to acceptable levels IME.
In any case, the series feed SE is going to need more turns to establish a proper low frequency phase characteristic( primary inductance ). Go parafeed and you've now( likely ), got a choke to put signal across...more an' more turns and C_winding...an' two inductors in parallel. Doesn't look like there is any advantage to one or another on these rather narrow basis-es...get a better OPT coil with good magnetic material and either one can stand out above the other.
Now, why not have a comment on this:
but PSE should be superior sonically to P-P( from among others )has far better peak current capability...
or won't you go and contradict another SE-ist?
cheers,
