I think Philips tied their EL scale plates directly to the hv winding of the transformer, though I seem to remember that a somewhat higher frequency is better. They didn't live too long anyway, but modern technology is probably better. You could tie a modern EL material to the 120V winding through a resistor. Most important is a symmetrical wave form.
