I don't have a Radio Shack catalogue handy but they carry a type of audio transformer used for multi-speaker installations in halls, churches, and such like that has a turns ratio that would probably do your job. The low power ones are also pretty cheap. Just drive the transformer with any decent oscillator circuit. -- Dick Rickert AT&T Consumer Products Laboratory
