The quality of the 120V run makes a big difference. For example, if it's a 15A branch circuit feeding multiple outlets across several rooms -- and if wiring is formed with pressure-contact receptacles, -- and the receptacle you need is on the end of the string, don't count on a stiff supply. By contrast, if a dedicated 20A branch circuit is run only to the shack, uses clamp terminals, and the feed is shared between the amp and a few low-current devices, then output power should be more predictable with minimal voltage sag at the 500W level. Anyone considering a new 120V circuit to the shack to avoid these problems (in my case it was dimming lights) may want to consider pulling a companion 4-wire 240V circuit to handle all commercial amps, new and old.
