   ALL TRANSISTORS ARE COMMON EMITTER, only its orientation with respect to   
   common is what changes.

   headlights. They pull 3 amps each because they are four ohms with 12 volts on   
   them. That adds up to 36 watts because watts are amps times volts. When you   
   have two of them in parallel    
   it is still 12 volts but now that pair of them is pulling six amps because two   
   four ohms in parallel comes to 2 ohms. So 12 volts times 6 amps is 72 watts   
   for the pair.

   shut up. When it doesn't    
   take a charge either put epsom salts in it or buy a new one. Do I have to be a   
   chemist to fix a Marantz amp ? (well actually there was this one...some other   
   time)

   it interesting. for one,    
   many innovators and inventors were either off the boat or first generation   
      
     here.   
      
     AND, even in the old days, some of them lived to be 80 or so. See, human   
   life span has not gone   
   up, the AVERAGE lifespan has. It does not mean the same thing, it just means   
   less people get killed   
   now. And now we're overpopulated, see, the old way was better.
