While I haven't had any experience with Fuzzy logic; I would like to
     tell you of my experience with Transistor Radios.

     Several years ago a friend of mine asked me if I could fix his 10
     transistor "SONNY" brand radio. I took off the back cover and counted.
     Sure enough, there were 10 bright shinny metal Japanese transistors.

     When we took the circuit board out of the case, turned it over and
     started to trace the circuitry, we noticed something strange.
     Although the audio output section resembled the normal push-pull
     stage; something was different. There were 4 transistors instead of 2.
     The extra transistors were connected directly in parallel with the
     normal output transistors.  "Wow!", I thought, "I didn't know that you
     could do that." In addition, there were 2 more transistors soldered to
     the circuit board with traces that went nowhere. Now, I became
     suspicious.

     I took out the transistors in the output stage and put them on the
     transistor checker. Two of them worked; two of them didn't.  I checked
     the two bad transistors with a meter.  There was no conduction between
     any of the leads. It was at this time my friend noticed the real
     problem with the radio, a broken battery lead. I replaced the 9V
     battery connector.

     When I started to solder the output transistors back into the circuit
     board, there was a loud snap. I turned the circuit board over and
     noticed that the top of one of the "bad" tansistors had blown off onto
     the work bench. This left behind three bare leads and a copious amount
     of black pitch. The bad transistors were in fact FAKE transistors.
