A brazed steel frame with luminescent mahogany powder coating, eight wrap 24 AWG hand wound coils with resin coating, a 47 μF capacitor, and custom cut springs. This is a pre-tuned shader that is set up to run at a speed of 95 CPS, at 7.0 volts. Good traditional  shader, and color machine. 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.
