[R-390] Audio Output Transformer

[James M. Walker]

Hi Group,
I run two R-390A receivers, and sometime back (years ago) I got the same
transformer from Radio Shack, actually a pair. They came with the wiring
info
on the back of the bubble pack. I used the center tap and one outside
connection
to the 390s' 600 ohm output, the other side goes to a pair of small studio
production
speakers, works great, sounds great. I also got the LS-204 on the panel pair
and
relegated the military version to a box as I really prefer the studio
speakers sound.
connection for me was blue and black to r-390A and red and white to
speakers.
As with all things, your mileage may vary.
