Okay, maybe I'm dense.

I picked up a few of those Cat# 32-1031 70 Volt 10 Watt PA System Line 
Transformers.

First reason:

    One of my R-390As was converted by its previous owner to an 8 ohm 
audio output.

I want to use one of these outboard to take the 8 ohm to the 600 ohm 
input to an Hallicrafter's R-42 Reproducer.

Can someone provide me with guidance to connect which tabs to connect 
the line to the R-42?

It IS clear which to connect the 8 ohm input.

Thanks in advance!
