I am repairing my B&W 51SB-B Single Sideband Generator and need the
following audio transformer:

Primary 20,000 ohms single plate 10MA DC
Secondary 500 ohms
B&W part # T-826

Does anyone have this or an equivent substitute that you want to sell?


Is the original transformer missing, or just bad?

There are no taps in it, right?

What kind of power level are you talking about here?

Scott,

The original transformer is still there, but the primary is open.

Yes, there are no taps on it.

The primary winding DC resistance on one of the other identical good
transformers measures 870 ohms. With a primary rating of 10MA it is a
low power transformer measuring 2 x 1.5 x 1.25 inches.

Thanks for your interest.
