This is a vintage Aiwa portable cassette player with AM/FM radio. Model number is HS-J300. I put batteries in this and the radio works (but you have to get the on/off button in just the right spot). I could not get the cassette player to work (the reels don't turn, including when I tested the rewind function). So I'm selling this as-is in hopes someone could fix the cassette deck. It's a sweet vintage collectable. Has some sticker residue on back and a label from a prior owner.
