Electrical terminal isolation block removal is necessary to get to all of the rust. The wires on the inside are soldered in place, which is easy to melt.

So nice. Bench tested to assure quality sound with a 6 volt battery. A 12 volt battery will work also, but the sound frequency is much higher. The screws are painted black as OEM.
