  • A better picture of the numbers on it would be helpful I think.

  •  

    My guess is Q1 on the schematic. Possibly a 2N222 transistor not required in most cases?

  • Hey, it looks like a temperature measurer.

    The colder it gets the more resistance it give and how warm it is the les resistance there is.
