Photos :)
Little minors scratches points on the cases painting but two are in clean shape and work perfectly.
Good for voltage gain in autoformer configuration with jfets buffers,
amplifier balanced input or single.
Have ground connection and magnetic shield (5)

Nice trafo.
But it looks like it can´t be wired with the primaries in parallel... they are already connected in series with a center tap.
Well, you can still use it for step down or step up, 1:2. Can be very useful. For instance, I have a power amp with only 3.6K input impedance (super symmetry inverting...). Wire it as a step down, and the impedances will scale by the square of the turns ratio. 3.6K is transformed to 14.4K for most of the frequency band. Just at very low frequencies the impedance will be closer to the DCR of the winding. To deal with that I drive my transformers with some series resistance. 1K sounds great to me. I see no need to drive a trafo from a super low impedance like most schematics do.
