No tuning, no fuss, no worries -- just turn on and operate ... includes AC power supply, 600 Watts output, continuous 1.5-22 MHz coverage, instant bandswitching, no warm up, no tubes to baby, fully SWR protected, extremely quiet, very
compact

--Ameritron's revolutionary ALS-600S is amateur radio's ONLY linear amplifier that uses four rugged TMOS RF power FETs -- gives unequaled no tune solid state performance.

--Includes ALS-600 Amplifier and a 120/220 VAC, 50/60 Hz AC switching power supply for home operation.

--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

--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 you'll hardly know it's 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.

--Separate ALS-600SPS switching power supply (included) can be placed conveniently out of the way and plugged into your nearest 120 VAC outlet -- no special wiring needed. Lightweight idea for transporting. Made in USA.

--Enjoy 600 Watts of no tune solid state switching power. Call your favorite dealer for your best price, order ALS-600S with power supply.

--Massive choke input filter greatly improves voltage regulations nd reduces peak AC line current.

--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 1/2 x 14 inches -- can be placed conveniently out-of-way.

--Wired for 120 VAC, supplies 50 VDC at 25 amps to ALS-600 amplifier.

--Adapts to 90-130 VAC and 185-260 VAC, 50/60 Hz.

--Draws less than 14 amps at 100 VAC and less than 7 amps at 230 VAC.

--Includes prewired cable to plugin to ALS-600 Amplifier.
