<font size="3">'''Every thing is already mounted on this image , but you can clearly see the small white connector just under the white wire support. It is a three prong connector with only two wires , a red and a purple/grey one.I used a Zaccaria knocker wich has a 50volts coil. Of course any knocker will do if it has a 50 volts coil . It is fixed at the side of the cabinet , and gives a good knocker sound ! '''</font>

<font size="3">'''I use the output to drive a small 6 volts realy , wich has contacts that can handle 16amps. At this contacts the knocker is connected .'''</font>
