#6. Record changer
Record changers allowed you to stack a selection of albums of 45s (seven-inch singles, not guns!) for your longer-term listening pleasure. Each record would make a soft slap sound as it dropped onto the turntable, a series of clicks followed as the remaining records adjusted into place and the tone arm swung over and lowered the needle into the outer grooves of the record. You’d hear the slightest scritch noise as the stylus settled just so into the vinyl and then the music began.
