I am trying to hook up an Ortofon TU-20 transformer (it is the actual transformer in an Ortofon T20) and I am not sure how to connect.
Can someone guide me?
See attached pictures
The Ohm readings I get are
Wires Left side Right side
striped -red 0,6 ohm 0,6 ohm
striped-gray 0,66 kohm 0,66 kohm
red gray 0,66 kohm 0,68 kohm
There is no continuity between left and right side. The gray cable in the middle has no connection with any of the other wires, so I assume it is ground.

I suppose this:
three wires each channel
You can measure the gray wire (from inside the trafo) , maybe common, with each one of the other red
The one with lower Rdc is primary, input from cart
The other, grater, the secondary, output
The pin jack isolated from box.
Then I will consider to solder the gnd of each channer together but not with the gnd connector

The diagram
I say primary and secondary, it is a autotransformer effectively with one nucleus.
it is an image took from web

Thank you very much for great input waltube. I will wire it up accordingly! I will have a go at it tomorrow and report back!
