What type of AC adapter plug does the Nakamichi Soundspace 8 receiver require? - nakamichi receivers ok, up toa point

I recently took my 8 Sound Space Nakamichi stereo, and I realized had no outlet for the recipient. I met the subwoofer, but I'm not sure if I want a 9 or 8-pin Sub-Committee for the recipient or recipients have its own connection. RTFM is not an option because the manual has long been discarded. Thank you in advance.
