Why, I wondered, do they use that series resistor? I had a hunch it is to create a hi-pass filter in combination with a parallel capacitance, but why choose such a hi-value R, when it might be more efficient to use a lo-value R and a correspondingly higher value of C? If you selected a 15K resistor, would you then also halve the value of the R in series with the input of the pos half of the drive signal? (It's 33K, I think. Did not consult the schematic.) Also, wouldn't you have to mess with the ground connections?
