Denon Cassette Recorder/ Player

DENON DN 730 R Cassette recorder and player with Dolby B & Dolby C

Here is a not very good video of a Denon cassette player recorder, ours is a DN-730R The review refers to it as a DN-730 but the person in the video calls it a DN-170. They both have Dolby B&C and look the same
