German nesting dolls (transformer question)

[laitue5]

I have a tranformer from an old tube milliamp-meter by R&S which I guess is a 5KΩ:50KΩ.

Do you think I can use it as an input or output for audio without tubes? Line in? But is there an opamp ready to “see” 50KΩ?

Achtung! Giant pics!

My brain is a bit fried from a late New Years.... but I work out 1:3.2

It's the ratio, the core material (which in this case may be unsuited to audio), and the wind that matter. Try it and see if you like it...... My .02c
