Ameritron ALS-500M Solid State Amplifier w/ ALS-500RC Remote Control ALS-500MR

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!

NOTE: For the 10m modification, both the 10/12m Mod (labor) and the 10m Mod Kit (parts) must be purchased.
