Josh: Years passed I used a mechanical rectifier to charge batteries until
the contacts eroded to thin to use.( about 50 years use) The system was
simple. a hores-shoe magnet, a coil, and a tuning fork type read contact.
The system was tuned to 60 cycles ( no hertz in those days) as the input
polerity was negative the contact was open, as the AC polerity was positive
the contact was closed sending 30 amps to the B+ and filiment battry banks
to run the radio. The charger also charged the Edison-cell lamps to use in
the mine. When the contacts wore out I replaced the contact with a diode.
