Note
The above performance data are original data. Own measured power at 50 Hz sine input signal:
~ 145 W into 8 Ohm
~ 225 W into 4 Ohm
Measured at an appropriate load resistor with optical control by oscilloscopes for a 'clean' output signal. Only one channel was measured under power. Because of the construction as a double mono power amplifier (separate power supplies) this power should be reached on both power amplifiers at the same time. Whether this power represents a continuous power was not checked, but these powers were reached cleanly over a period of about 15 minutes. After that, the measurement was stopped to protect the load resistors, as they were not sufficiently dimensioned in terms of power.
The output stage has a switch-on delay and a protection circuit. This protective circuit is partially sensitive to mains interference. A sufficiently dimensioned mains filter can remedy this.
