It's an impedence matching / isolating transformer. probably intended for telecomms equipment.

Looks like an old line transformer. With a 30k primary it is probably a plate-to-line job.

could this thing be used as an audio output?
30K CT primary to 50 secondary gives me 4.8K CT to 8 ohms which is pretty classic. (PP of course) But I wonder if this thing may take it and how much could it handle? |

Note the 'max 8dB' spec (if I read it correctly). Not much good for O/P. You could use it for matching, say, a low impedence microphone to an input though.

8 dBm = 6 milliwatts. That's one of the UTC "Ouncer" series.

reverse it...50 Ohm -> 30 kOhm for a mono MC cartridge input(?).

This is a push-pull plate to line out transformer...
Catalog page: http://www.bunkerofdoom.com/xfm/UTC_...56_14_0001.jpg The O-series "ouncer" is pretty hi-fi. We used to use them in broadcast equipment where space wouldn't allow an "A" series... I would think it would also make a decent mic input transformer, or maybe an MC stepup. Pete |

And it's worth some good money if you have one or a pair of them. Unless you are going to build a transformer coupled line stage you might consider selling it/them on eBay and applying the funds to something more suitable.
