What info do you need?  Most of it is painted on the can  ;D

5.5v would be about +17dBu, your ratios are there, frequency response, expected load...

..it's the 13.585 that is your model no., the "Type 3.15M" is just the general size/core type designator

Ah, yes.  The "M" is for mu-metal.

I've got a pair of Jorgen Schou ST3450

As far as I know these are CT input transformers, but that's really all I know.

Nothing comes up with Google, so if anyone has info on these ?
