Have you tried measuring the AC input voltage drop, no load versus key down max? A Kil A Watt meter is a handy instrument to have for this. My drop with 120V input is less than a volt with the KPA-500.I would say if drop is 2V or less, it is not worth the expense to have an electrician run a 240 volt line. My AC line voltage runs an average of 122V on my 24/7 monitor. Mike AC5P

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?
