Raysistor by Raytheon Model CK1106 Optical Isolator / Switch
Product Description
These are hard to find! A real museum piece this one. A raysistor is an optically coupled device used in vintage equipment for volume control and switching applications. This particular unit is a high voltage model and is larger than most. Unused and in very good condition, this could be a good addition to any collection of vintage electronics. Comes with original box (slightly tattered and one flap missing). We also have an 1108 but no box. Inquire for that one.
