Yes Ed. I do mean a choppert or read rectifier, but not a modern two contact
thing. The rectifier is a model t magneto type magnet and a solinoid coil to
a 1" x 2" steel plate like an old earphone or early high impedance speaker
made about the turn of the century.You are old enough to rember the cone
speakers. The read is a single tuning fork that beats againdt a contact at
60 cycles and produces DC out.
--   A mgnetic rectifier is nothing more than a magnetic amplifier biased
beond cutoff to send only one polerity out Ie  Dc out.  They worked very
well when you and I were kids and they work well now.
