You can now purchase the ALS-500RC remote control unit for your ALS-500M! If the serial number on your ALS-500M is below 13049, you will need to purchase the ARF-500K remote kit as well.

--Mobile no tune Solid State Amplifier -- uses four rugged 2SC2879 high power linear RF power transistors.

--Instant bandswitching, no tuning, no warm up -- just turn on and operate -- makes mobile QSOs safer.

--Very Compact -- Just 3 1/2 x 9 x 15 Inches -- fits in nearly any mobile installation; weighs only 7 pounds.

--Extremely quiet -- quiet low speed, low volume fan stays off and silent until temperature rises.

--Output Power -- 500 watts PEP, 400 Watts CW
Continuous Coverage -- 1.5 to 22 MHz 10/12 Meters with easy to install optional kit.

--Load Fault Protection -- disables and bypasses amplifier if antenna has excessively h high reflected power or if bandswitching is set lower than exciter frequency -- virtually eliminates damage because of operating error; has Load Fault LED indicator.

--Thermal Overload Protection -- disables and bypasses amplifier if temperature is excessively high; automatically resets when temp drop to safe level Thermal Overload LED indicator.

--Excellent harmonic suppression -- multiple section output network, push-pull output circuit has excellent harmonic suppression.

--DC current meter lets you monitor collector current.

--ON/OFF Switch -- bypasses amplifier for "barefoot" operation without having to disconnect high current power supply cables.

--Remote ON/OFF Control -- lets you remote control ON/OFF function for out-of-the-way mounting of amplifier.

--Exciter Drive -- less than 100 watts input gives full output.

--Power Supply Requirements -- requires 14 VDC at 80 amperes peak current for PA transistors and separate line for 14 - 16 VDC at 4 amperes for control and bias circuits. Made in USA.

* Due to limited supply, we occasionally drop ship amplifiers from the factory.
