Universal audio frequency power amplifier 5 Hz - 1 MHz for magnetic field im- munity testing, 60 V peak, 40 A peak, protected against overvoltage, short at the

output or overtemperature. For frequencies < 15 Hz a minimum load of 1 Ohm at the output must be connected, e.g. SHUNT 9571 or NFCN 9734.

Universal matching network with built in shunt resistor to compensate for the

inductance of Helmholtz coils, GPIB or RS232 controllable.
