Same as an ALS-600 but without the power supply. Must Purchase the ALS-600PS separately. -Ameritrons revolutionary ALS-600 is amateur radios ONLY linear amplifier that uses four rugged TMOS RF power FETs - gives unequaled no tune solid state performance. -Includes Ameritrons no tune FET Amplifier. -Instant bandswitching, no tuning, no warm up -Output Power - 600 Watts PEP, 500 Watts CW -Continuous Coverage - 1.5 to 22 MHz; 10/12 Meters with easy-to-install optional kit, $59.95 plus s/h -SWR Protection - prevents amplifier damage if you switch to wrong band, use wrong antenna or have high SWR -Over Power Protection - if output forward power or reflected power exceeds safe level, output power is automatically reduced to prevent amplifier damage by controlling ALC to exciter. -Extremely quiet - low speed, low volume fan is so quiet youll hardly know its there, unlike noisy blowers used in other amps. -Very Compact - 6 x 9 1/2 x 12 inch amplifier takes up less desktop space than your transceiver and weighs 12 1/2 pounds. -Illuminated Cross-Needle SWR/Wattmeter - lets you read SWR, forward and reflected peak power simultaneously -Operate/Standby Switch - lets you run "barefoot", but you can instantly switch to full power if you need it. -Front Panel ALC Control - exclusive Ameritron feature - convenient front panel control lets you adjust your output power. -Transmit, ALC SWR LED indicators - keeps you informed. -12 VDC output jack - lets you power low current accessories. -Massive choke input filter greatly improves voltage regulations nd reduces peak AC line current. -Ameritrons exclusive Multi-Voltage Power Transformer lets you compensate for stressful high line voltage and performance robbing low line voltage. -Step Start Inrush Protection stops damaging inrush currents and extends life of power supply components. -Illuminated Cross-Needle Meter monitors voltage and current of 50 VDC line. -Extremely quiet fan. -Very Compact 6" x 9 ½" x 12" - can be placed conveniently out-of-way. -Wired for 120 VAC, supplies 50 VDC at 25 amps to ALS-600 amplifier. -Also use on 100-130 VAC and 220-250 VAC, 50/60 Hz. -Draws less than 12 amps at 100 VAC and less than 6 amps at 230 VAC.
