Adding an Ericotone "tweeter" ringer to your American K7 or K14 Ericofon

addtone1.jpg (18678 bytes) The Ericotone ringer is a circuit board, mounting bracket, and choke coil in one unit. The mounting bracket is different than that used on the K2 and K4 chassis, and are not interchangeable. The mounting instructions are the same, but I myself have no K4 mounting brackets.

As you can see, this is going to be much more involved than adding a buzzer. You're going to have to do three solder joints on this.

Be very careful soldering, it's very small work, and easy to mess up with a hot soldering iron. Check carefully when finished to make sure you don't have any cold solder joints or short circuits.
