[Boatanchors] Collins 75S-3C audio output transformer

[n2lxm at juno.com]

Greetings All, 

        While setting up my new operation position, I found that I had no
audio from the receiver. I pulled it to the bench and found that the
audio transformer has an open primary. Trying to find and information on
the transformer(primary impedance) has come up short. Tried NSN
667-0302-000, found plenty of E-bay hits, but no spec's. Dose anyone know
what the primary impedance is. The tube data for the 6BF5 shows class 1A
as 12 K, which seems a bit high. I pigged tailed an old AA5 output
transformer in and it works. And help would be greatly appreciated.
