"A vintage/original Kenwood Model KR 6170 "Jumbo Jet" Stereo Receiver w/just about every gizmo you could think of - including Guitar Inputs, a Reverb Unit, Foot Switch Jack and a Electronic Rhythm Composer aka Analog Drum Machine/Beatbox. You can check out this YouTube demo video to see a similar working unit (not the one I have listed) in action (you may want to scroll towards the end of this video & skip the intro.)"

"Here is a demonstration of a Kenwood KR-6170 that has been in our family about 30 years.
Also shown are the cabinet and speakers. I made an error in the narration when I said the speakers are TEAC. They are in fact Sansui speakers."
