A brazed and blackened steel frame, with eight wrap 24 AWG hand wound coils with resin coating, a 33 μF capacitor, and custom cut springs.  This machine has two geometrically different front binding post holes drilled in the side plate making it possible to change this shader to an outliner if so desired.  This is a pre-tuned shader that is set up to run at a speed of 100 CPS, at 7.0 volts. If you are looking for a machine similar to this one, but have different set up and tuning specifications, you can place a custom order and have one built for your particular needs.
