Finally! A replica 412 battery!
 

I've flirted with the idea of building one of these, but it finally took a client to give me the final shove. He has a Regency TR-1G--the one that he'd had as a kid--and wanted me to see if there was a better way to power it. Eveready still makes the 412, but they're short-lived.

My replica takes up the same space as an original, but uses two 12-volt garage door opener A23 batteries, easily replaceable. I even made the outer sheath look like Regency's own version, the Number 215.

Despite the higher voltage, my TR-1 took in the battery with open arms, and played for the first time in ten years.:banana:

It's just about the smallest replica battery I've ever done.

That battery really is a pro job, Bill. Can you explain what the case components are? Looks sort of like a triple-A battery holder cut down? Then what's the outside of the case made from? But no need to reveal any trade secrets! Thanks.

Actually, the holders are for N cells. The A23 batteries are N sized, so it's a drop-in solution.

Very simple--just circuit board, N cell holders and Masonite.
