Thanks; I'll look for it. Somewhere here I have a Maxim application
note describing very accurate (~0.5� match) over a very wide audio range
and will have to look for it. I've built much simpler circuits to use
in driving two-phase motors over a 4 to 1 speed range and even they
should be just fine for single-frequency operation.
