Note
The MFJ-216 Deluxe Amplifier Saver relieves temperature related stress on amplifiers, tuners, and dummy loads while allowing proper system adjustments.
It allows amplifiers to be properly adjusted without the use of long steady carriers, and allows tuning of an amplifier with full required drive from the transceiver without over-heating the finals or anything else in the RF line. It sends a series of pulses to the transceiver allowing the peak power to be high enough to drive the amplifier to full power, but with the average power being low enough not to over-heat the final(s).
The MFJ-216 works with any solid state amateur transceiver or transmitter, and all other equipment using positive keying line voltages below 50 volts open circuit and 100 mA closed key current. It can also
be used with negative voltage key lines (commonly found in older tube type radios) provided keying voltages are below 25 volts DC open circuit.
