   Gentlemen,   
      
   Having put together a dim bulb tester for current-limiting purposes   
   and fired up the faulty 'scope, this component gets hot. I'm not   
   really sure what it is, though and there are no markings on it at all   
   except for two tiny blobs of paint.   
   Anyone know?
