Yes I do agree with Jim, K9YC. However, should the amp be powered
from residential electrical outlets where there are usually 4 or 5 on
the same circuit and using the stab-in connections, the 120V voltage
drop may be excessive under full load. The amp should not display the
HV to be less than 60 volts at 500 watts output. If it is less than 60
volts, I would question the line regulation of the 120 volt service.
Refer to the KPA500 manual, page 16, paragraph #3, NOTE on this topic.

The amp runs fine on 120V, and changing to 240V is trivially easy.
