Help with this transformer, please?

Hey boys and girls,

I got 5 of these bad boys from a member here:

They're mic input transformers in a sealed can with a 9 pin base. There's something printed on top that says "TYPE 94-0117 - MADE FOR RCA VICTOR COMPANY, LTD. MONTREAL, CANADA - MADE IN U.S.A.". They look old, too.

I measured the DCR between pins and here's what I got:

Pin1 - Pin3 = 7.8 Ohms
Pin3 - Pin4 = 9.1 Ohms
and
Pin1 - Pin4 = 16.9 Ohms

Which makes sense, right? This is, I believe, the (off-)center-tapped primary.

Pin5 - Pin6 = 148 Ohms

Which must be a secondary - nothing unusual. I feed 100mV between 1 and 4 and get 245mV between 5 and 6.

Pin7 is not connected, but here's where it gets weird:

Pin2 - Pin8 = 274 Ohms
Pin2 - Pin9 = 370 Ohms
Pin8 - Pin9 = 96 Ohms????

What the??? How is that possible? I decided to sacrifice one in the interest of science, but it's potted inside the can and hard to get it out. I might break out the heat gun and the Dremel later tonight, but in the meantime: what do you all make of this?

Peace,
Al.

370-274=96.
nuthin weird about that.

Pin2 - Pin8 = 274 Ohms
Pin2 - Pin9 = 370 Ohms
Pin8 - Pin9 = 96 Ohms????

pin2 -- 274Ω -- pin8 -- 96Ω -- pin9

Pfft! I'm an idiot.

Peace,
