Dead Batteries

[David Dunlop]

Hi Wayne.

When I cleaned the originals to see what they were, they were basically brown, phenolic circuit board material. I went to the local Radio Shack store at the time and bought a solid, copper plated circuit board kit that included a pen and a bottle of etching solution. I tossed the pen and applied the solution to the entire board (it was only 6 inches square) to strip all the copper off.

I then traced the pattern for the two plates onto the board and cut them out with a hack saw as I recall.

The copper etching solutions are readily available on the web, but I am not sure who in Canada still sells the solid, copper plated PCB’s.

Hope this helps, Wayne.
