The actual waveform produced at the transformer secondary depends upon the
turns ratio of the transformer used, the series resistance on the primary side
used to match the line, the output impedance of the amplifier, the on-resistance
of the amplifier while providing the transformer ground, and the transformer
winding resistance.To ensure that the amplifiers can drive the reflected load, it is
