[R-390] 600 to 8 ohm speaker converter

[Les Locklear]

That is a 70 volt line transformer. On the other side from what is pictured you should have a 10 watt tap,  that will connect to the audio outputs of the 390. Then connect your speakers to the correct ohm output 8, 4, etc.

When I got my R-390 it has what I assume to be some kind of transformers to allow a modern 8ohm speaker to be hooked up.  I did not think to diagram how the wires were hooked up.  Is there any manual that tells a non-electrician how to connect these transformers to the R-390A to let me listen without headphones.
