identify utc transformer

[pepper]

Hello need help identifying these can not find any info on the web or what they can be used for

They are for impedance matching or line out duty for Transistors Circuits development.

Thanks I'll have a look

wonder if you could spin them backwards for use as a step-up transformer for a low output moving coil cartridge. Seems a little bit overkill but it might get the job done.

found this seems useful

Might also work for a headphone amp.

I sold a ton of line matching transformers on eBay earlier this year. Those will fetch good coin if you don’t have a use for them. Especially if you ship internationally.

Wicked rare, I've never seen a set loose. They were meant for use as a transistor interstage for amplifier prototyping. That road was quickly turned into a dead-end.

They're step-down transformers which can be configured with 5:1, 10:1 or 20:1 ratios.

Yes, that's a distinct possibility.

Oooh, those are neat-o!
