Those will explain "bucking" with regards to saturated reactors...

No need to bother, I already understand that as I think I stated in a
previous post, that's why I suggested in my first post in this thread
that perhaps the "two "secondaries" were wound on the two outer legs of
the E-core. This whole discussion has been an unfortunate result of my
misunderstanding what physical construction you were taking about,
somehow I got the impression from your first post that you were
describing a reactor where all three windings were on the central leg of
the E-core, when you didn't respond to the suggestion in my first post
that perhaps the "secondaries" were on the outer legs of the core, the
misunderstanding was cemented in my mind. In a later post where I
reported on the GE E-155 circuit I discovered, which did work the way I
speculated, you did respond with "Not news - this would be common for a
saturable reactor." I took that comment as a general comment about
saturable reactors, specifically not applying to the S-W reactor.
Looking at it again I assume this may have been another
misinterpretation on my part and although you didn't explicitly say so
you were actually talking specifically about the S-W reactor there.

I think we are finally on the same page and now that I understand that
you weren't talking about a reactor with all three windings on the
central leg, if I were to go back and read all of your posts in that
light I would probably find that they make perfect sense.

As far as "basic" operation - the use of the buffer tube isolates - wait
a minute - didn't I do this once already? Never mind.

Exactly, the use of a separate "buffer" tube is not necessary to the
operation of the circuit, it is merely an elaboration of the circuit,
perhaps to increase the tube count as was popular at the time.
