Magneto E-Stim #4
Magneto and bell assembly from a Leich 901 telephone from the 1930’s mounted on a bamboo board. These magnetos were much more powerful than the bar-magnet magnetos of earlier years. The magneto is connected to 3 light bulbs and a switch that engages the bell unit. Finally it is connected to a potentiometer to further adjust the current output and then to the post/banana connectors as well as the 3.5 mini-phono jack.
