Default Stewart-Warner reactance dimmer

a bunch of stuff...

Let me add a point... when I originally looked at the schematic - the
saturable reactor was drawn as a transformer - though it didn't take
long to figure out that it had to be a form of saturable reactor rather
than a transformer... (being an early schematic, I doubt the "standard"
for indicating saturable reactors had been established, and certainly
not yet in common use).

That only leaves figuring out whether the S/W is a two or three legged
configuration (are the two load windings on the same leg). As noted - a
picture might tell a lot. Also - note that the GE version is a fully
buffered (isolated) and driven system - while the S/W's system is part
of the RF / IF B+... the differences make a significant impact on how
the two circuits act (and interact)...

best regards...
