The KPA500 does quite well with generators, especially the Honda family. These days it is the amplifier of choice for many DXpeditions who’s only power is provided by generators.
Since the KPA500 has a linear supply, it is not troubled as much by modified sine wave generators and investors as those using a switching supply. 73!
