The output of the 7500 can be offset ±200 volts, open-circuit, by means of a front panel DC offset control. The 7500 provides selectable input coupling, either direct (DC) or capacitive (AC).The amplifier's output is protected from short-circuit or other abnormal load conditions by a unique output protection circuit, that uses a modified form of foldback current limiting. The output stage is convection cooled by a special heat sink configuration. Output Power, Voltage & Current (Specifications apply using a 200 ohm resistive load). Power: 75 watts, DC to 100 kHz; 40 watts at 500 kHz; 10 watts at 1 MHz. Voltage: 125 volts RMS, DC to 100 kHz; 90 volts RMS at 500 kHz; 45 volts RMS at 1 MHz.
