You are bidding on a UTC A-27 audio transformer.  Here are the specs:

Primary: 100K (two windings in series; should be good for 25K if connected in parallel)

Secondary: Two tapped windings, that can match the following: 50 / 125 / 200 / 333 / 500 ohms

Maximum level: +15 dBm

Frequency response: 30-20,000 Hz (very high-fidelity).

Item is used; I will clean the solder off the lugs.

Sold as-is; guaranteed not DOA.

Thanks for looking, and happy bidding!
