It’s time to take another look at an old dogeared magazine and look at some vintage tech and music trends of the past. This month, we’ll flip through this February 1966 issue of Playboy which, although not exactly chock full of ads, does have two notable features … HEY! Get your mind out of the gutter.

Fifty years ago this month, that venerable men’s magazine of many of our youths put out a “historic” issue, featuring its first pair of Playmates, the identical twins Mary and Madeleine Collinson. We thought this occasion – Playmates in stereo, as it were – might afford us an opportunity to take a look at what of the latest and greatest in hi-fi was being spotlighted and advertised in the pages of Playboy that month.
