Hidden Secrets In A 1955 Home
This person must have done some serious snooping because they discovered this panel behind a hidden door in a 1955 home. These plugs could be used for a multitude of things, which is why they asked the internet for help. Is it something innocent, like speakers for audio? Or something more sinister, like harsh medical treatment?
Luckily, the users of Reddit were quick to identify the plug and said they were ¼” jack plugs. You can’t get more specific than that! Based on the size of the wiring, they’re audio based. We still wonder why it was behind a hidden door though (via Reddit).
