Well, my trusty AT&T phone died and a got a new one.
So,i thought to take apart the handset..err..BASH apart,as it was
*NOT* made to be taken apart in any nice way.
Surprise!
The electret mike had a _diode_ (signal) in parallel, reversed polarity.
Say what? Waffer??
And the dynamic speaker had _two_ diodes (1N4000 series),
back-to-back in parallel across it.
Say what? Waffer?
Yes,i know that diodes are cheap, but since there is no useful
function for them, what gives?
