I have been using an ALS-600, the 600-watt Ameritron solid state amp, for two years. My shack is wired for 120 volts, 20 amps, 2 circuits.
The voltage from the power supply drops only slightly when transmitting, almost surely from internal factors, not house wiring. The AC mains voltage does not drop. I have never tripped a breaker. The Elecraft Amp is probably more power efficient than the ALS-600 with its sophisticated power supply. I'd worry about something else. FWIW.
