Sure they are       working when they are conducting, but they are also working when not       conducting. They are blocking.

I won't be as mean as you but I       will say it - ijiot ! YOU pick the diodes, they don't pick you !

Got any       idea why the hell this Carver Receiver (MX-130) turns off the tuner when I       turn off the speakers ? I decided to get away from it, and now I think I have       a clue, it switches by        relay, maybe somehow the 12 volt line is getting shorted... I'm just here to       take a break from it.       > I had a computer that would reset when I turned off the amplified       > speakers before turning off the computer.
