I've been going through some transformers to see what to keep and what
to lighten the load, so to speak. I found one that I can't quite figure
out. The thing is about the size we'd see on a 60's TV set. Nice piece
of iron and useful. The issue is this: There are four sets of windings.
The B+ set is easy, color and resistance are consistent with the
winding. There are 3 other windings. One is identifiable as the 5v
filament winding, another as the 6.3v winding, leaving what I believe is
the primary (blinding glimpse of the obvious?). There are 3 wires left
over for (what I believe is the primary. One black lead that pairs with
another dark color wire. They ohm out as would a primary winding; that
is, low resistance but an obvious inductive reactance. The bug is that
there's yet a third wire associated with this pair and the resistance is
several hundreds of ohms in relation to the other two. Any ideas? It
can't be a CT, of course, and its way too high resistance to be a 220v
tap. Also, the wire size of the "primary" is #16 and this outrider is
maybe #18 or #20. I didn't just fall off the turnip wagon but this is a
poser?
