This is the rear view of the the receiver. Somewhat unusual is the ability to connect 3 pairs of speakers to it, though only 2 pairs can be connected at one time. It was purchased by my friend while he was in the Airforce in England, so when he came back to the states he had to put on a different AC power plug end and switch input voltage selector for 110Vac. Looking at it now I have some regrets about selling it..
