this transformer origins from the input section of a portable emt mixer. i don´t know the manufacturer of the transformers,since the the laminations came from the other side of the pond, but the copper wire diameter & shielding thickness has european sizes.
the winding data per coil:
inner layer: primary 3 x 200 (600) turns - 0,15 mm wire, seems handwound.
copper shilding 0,1 mm
outer layer: secondary 3 x 600 (1800) turns - 0,1 mm wire
used lamination type is 375 UI (the ones without holes in the pictures)
alloy probably 80%NiFe
beside the differences in size you can also see the difference of the alloy.
i unwound the secondary on all three sections of the coil, and counted one primary before i rewound the transformer.
