If you don’t know what this is, you’re probably not old school and more than likely you don’t know what true high fidelity sounds like. Back in the day, your music was delivered up on vinyl in two flavors, long play albums (LPs) and singles. Despite the name, singles actually had two tunes on them, the featured song and a flip side or bonus song. Most turntables at the time were set up to play albums that had a small hole in the center. 45′s were made with a larger hole that allowed easier handling by a jukebox. This required anyone wanting to play a 45 on their home stereo to pop an adapter into the center of the record so it could be held by the smaller spindle of our turntables. Hence the 45 adapter disk you see on the button above.
