The following tables contain information on measured current consumption as well as calculated heat dissipation during what we see as
the most extreme sustained normal operation (1/8 rated power).

*1) The amplier’s PSU operates as a non-resistive load, so the calculation “Volts x Amps = Watts” would not be correct. Instead, measured and specied here
is what is known as the “Active Power” in the amplier providing useful, real-world values of power consumption and heat dissipation.
*2) Current draw gures measured at 230 V. as well as 120 V. The efciency is similar, but not identical for the two scenarios. The efciency for 100 V mains is
very similar to that of 120 V.
