[Elecraft] Question about 120 volts vs. 240 volts house supply to KPA 500

[Bernie and Cheryl]

Dear Folks:

I have operated my KPA 500 off of a normal wall out let (120 volts) for 
years now and have gotten good service.  However, I've often wondered if 
there would be a definite advantage to getting 240 volt service into the 
shack, so that I could operate the amp off of that supply, as opposed to 
a normal wall outlet.  I recognize that there would be less current 
draw.  My question would be whether it would lessen the wear and tear on 
the amp if I switched to 240 volts?

Thanks and 73 de Bernie, KF0QS
