I'm wondering if those old 110V DC motors care if they're run on a
pulsating DC with an average voltage of 110 volts, or if they really
prefer to be run on Thomas Alva Edison's original pure, no-ripple
120-volts accept-no-substitutes direct current.  It probably doesn't
matter a bit.  Some of the old solenoids might care, however.
