AMERITRON ALS-600600 WATT NO TUNETMOS-FET AMPLIFIERINSTRUCTION MANUALThe Ameritron ALS-600 is a 600 watt output,solid state,linear amplifier using state-of-the-art,high voltage,RF TMOS FET devices in the power output section.TheALS-600 provides continuous frequency coverage from 1.5 through 22 MHz with notuning adjustments.Broad band 5 pole low pass filters provide output harmonicsuppression in excess of all FCC requirements.Export modifications are available toextend operation up to 30 MHz with a copy of a valid amateur license.The ALS-600 uses four MRF-150 FETs operating a 50 volts in a double endedpush-pull parallel output configuration.High quality RF components combine withan accurate peak detecting directional coupler,front panel adjustable ALC circuitwith automatic SWR fold-back,and one switch frequency selection to make this oneof the easiest to operate amplifiers available.The matching power supply,ALS-600PS,is shipped factory wired for 120 volt,50/60 Hz power mains and is easilyconverted to other supply voltages between 100 and 240 volts.PLEASE READ THIS MANUAL BEFORE OPERATING THIS EQUIPMENTAM云习的116 Willow RoadStarkville,MS 39759 USA662-323-8211Version 2 Printedin U.S.A.
