The drive-in speaker said “does not work.” And it was full of sand. But that’s not the BIGGEST mystery here.

These drive-in speaker restoration projects are becoming more and more fun.

Case in point.

A few weeks ago, I acquired an RCA drive-in speaker from an eBay seller. I was intrigued by the unit, especially because the back of the chassis had the words “DOES NOT WORK” scribbled on it.

Okay, I like a challenge.

And after I finally cracked the speaker open … i discovered not only the reason why it didn’t work, but that someone had scribbled a very cryptic message on the chassis’ internal case.

This challenge just became more challenging.

And in the end, I was able to restore the unit, give it a nice repainting, and demonstrate that it works – as well as determine what that cryptic message meant, and how it helped me determine where this speaker once operated.

And … of course … it’s all on YouTube. Because I’m getting a real kick on restoring these bad boys and posting my progress.
