I think some clarification might help, "polo." Are you saying the US cleaner cycles between low amplitude and high amplitude, or switches between two different oscillator frequencies? The switching, whatever it is, you imply takes place at the 60 hz line frequency, which would certainly simplify circuit design.
Your use of the word 'phase' was just to refer to the two states the drivers switch between, right? Sometimes you have to read a little deeper between the lines, Marshall. <grin> Mike D. > Ok, thanks for that info, but nevertheless, this tidbit does not change > the fact that ultrasonic cleaners are designed to have a low and high > phase.
