Note the phonograph (amp) option in the upper left corner. So this R version radio (remote) also has the phono option that could be used for an MP3 device - no I don't intend to.
I am not going to wire in the remote box on its 12 conductor cable at this time, but display the remote its self near the radio. The big cable is not that attractive. It originally used a flat cable and one of those grey ribbon cables would work, but, not for now.
On the video below, the remote tuning functions are demonstrated by the duplicate pushbuttons on the control panel. Note the movement of the tuning knob and the lack of a on/off/volume knob. The small knob is local/distance and the phono/radio switch is part of the assembly with the switch on the back.
It should also be noted that this radio has a very high center of gravity and a small base. Care must be taken not to knock it over especially if small children or guys with footballs/etc. are in the room.
