Open Box Ameritron ALS-500m 500W Solid State Amplifier without Remote Control Head S/N:15469

Amplifier never used, box was opened to verify everything intact

Features:

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.
