Good odd test equipment you never see anymore
Just picked up this Sun CCT-20 made for the military. Coil/ capacitor tester, about 1970. The outside of the case has some rust, but the "guts" have no damage and are in nice shape. Id does not work quite right and I'm pretty sure "dirty switches." The switch on the bottom right is going to be difficult, as it's a momentary rotary, "center off" and quite a lot of spring force. Somewhat difficult to operate, and you must cycle it many times to "wipe" the contacts clean. I guess I'll put a larger knob on there temporarily until I get it cleaned up
Contains a 12AU7 tube, and a "vibrator" which is the mechanical grand-daddy of the modern switching inverter.
