Introduction
Thank you for purchasing this amplifier system.
The ALS-606 is a compact 600-watt nominal PEP output amplifier. It uses an external
power supply system. This amplifier covers 160-6 meters. Nominal drive power is 75-
watts or less. NOTE:
This amplifier excludes all operation between 25 and 28 MHz.
The ALS-606 interfaces with most modern amateur radio transceivers. Supported band
data input includes ICOM compatible analog voltage, Elecraft and Yaesu BCD band
data, and Kenwood serial data. With proper interface cables and data, this amplifier will
automatically change bands in step with transceiver band changes. Automatic band
selection using a band data port or band decoded bus requires purchasing an Ameritron
interface cable for your radio.
Carefully unpack this amplifier and power supply. Please inspect everything for physical
shipping damage; this includes cabinets and chassis. Ameritron does
not package
dented or damaged units. Cabinets and controls can be broken, bent, or dented with
rough handling. If a new unit arrives mechanically damaged, including broken knobs or
switches, it is
always from handling somewhere between Ameritron and the end user. In
the event of cabinet damage or broken controls, please contact the dealer immediately.
To permit claim processing, retain all boxes and packing materials.
The Ameritron ALS-606 is 600-watt nominal output, 160 through 6 meter amateur radio
band, solid-state amplifier. The ALS-606 uses four 50-volt linear RF MOSFETS. These
MOSFET’s are specifically designed for linear power amplifier applications, rather than
non-linear or pulse service. They provide lower SSB distortion when compared to non-
linear application solid-state devices in SSB service. Fan speed is regulated by
temperature sensors; assuring conservative cooling with minimal noise.
Nominal driving power is 75-watts for 600-watts output (approximately 9 dB gain) on
most bands. The compact 9-1/2” wide by 7” high amplifier package (depth only 14”) fits
nearly any station configuration. This attractive desktop amplifier unit weighs
approximately 15 pounds.
An external 50-volt 25-ampere CCS power supply powers the ALS-606. Two different
supplies are available. The ALS-600SPS switching regulated supply and the ALS-
600PS unregulated supply. These supplies operate on all standard residential power
line voltages.
Caution: This amplifier has an FCC mandated automatic disconnect and other features
preventing 27-MHz operation . There is no available circuitry or control provision to
circumvent this lockout.
Please read the manual completely and understand the operations before trying
to operate this amplifier.
