  • I ordered one of these but instead received an Electro-Magnetic Transducer. The markings read: CET 12A3.5 13 501 And it is very similar to this one: http://www.chinasound.com/Product/CET/CET12A3.5-42-2.0R.htm

  • Agree ! I was thinking why did you choose to cut the black and not the white one. I imagine it is because if you are interrupting the white one then if you put your finger in the outlet, even if the relay is open, you will get a discharge, while by interrupting the black one, when the relay is open nothing will happen if you touch the outlet.
