*1) The amplifier's PSU operates as a non-resistive load, so the calculation "Volts x Amps = Watts" would not be correct. Instead, measured and specified here
is what is known as the "Active Power" in the amplifier providing useful, real-world values of power consumption and heat dissipation.
*2) Current draw figures measured at 230 V. as well as 120 V. The efficiency is similar, but not identical for the two scenarios. The efficiency for 100 V mains is
very similar to that of 120 V.
