I am going to use 2 x Lundahl 1544A transformers to convert a 650ohm balanced output on my preamp to a 100k ohm unbalanced input on the power amp.
What is the best way to wire it?
Here is the data sheet for this transformer:

I am looking at R4B:L1 connection right now. This is a 4:1 turn ratio and should attenuate by 12dbs which the unbalanced input is looking for.
But I have heard 1:1 is okay as well. And on R4B connection, where does pin 11, 13, and 14 go? I won't be sticking these transformers in a chassis.
