Crutchfield Customer Review (What's this?)

an electronic device with two connections an ANODE and a CATHODE, Rectifier diodes allow an electric current to flow in one direction and may be uses as convert AC to DC, or may be used as a protection circuit to protect DC devices! There are also lots of specialty diodes that serve other purposes such as voltage regulation The common rectifier diode may be used to replace the rectifier vacuum tube!

Pros: Worked perfect have a working TV now!!

Cons: None
