Ameritron AL-800H Verstärker
Modell: AL-800H
Kategorie: Funk und Kommunikation
Gruppe: Verstärker
Beschreibung: 1500 Watt Linear Amplifier
                                    The Ameritron AL-800H is a 1500 watt output linear amplifier
that operates from 160 through 15 meters.
The AL-800HX is the export model that operate from 160
through 10 meters. Export modification
instructions are only available with proof of a valid
amateur radio license.

· The AL-800H uses two reliable high gain 3CX800A7 tubes.
· A time-delay circuit provides a 180 second warm-up to
eliminate potential damage to the tube
· A grid overload circuit quickly disables the amplifier if
the grid current becomes excessive. This
feature prevents excessive grid current from causing
distortion or damaging the tubes or other
· A thermal overload automatically disables the amplifier if
excessive heating of the power transformer
· A multi-voltage heavy-duty transformer with a unique
"buck-boost" winding allows adjustment of
the primary voltage to 14 different voltages centered on 115
and 230 volts. This versatile Ameritron
feature allows the user to select the optimum primary
voltage for maximum performance and life.
· The tuning and loading controls have vernier 6:1 reduction
drives for smooth tuning. Logging scales
allow quick and repeatable control adjustment for rapid band
· The AL-800H has two illuminated cross-needle panel meters.
the left meter provides a continuous
reading of grid and plate currents. the right meter reads
peak RF power output on one scale and Plate
voltage (HV), Reflected power and SWR (REF), ALC detector
voltage (ALC), and ALC adjustment
level (ALC SET) on the other scales.
· Heater and plat voltages are maintained using the
"STBY/OPR" switch. This allows the amplifier to
be conveniently bypassed for "barefoot" operation.
· A front panel "ALC SET" control allows convenient
adjustment of the ALC threshold. The unique
ALC circuit samples the grid current and power supply voltage.
· "XMT" and "OL" LED's on the front panel indicate proper
operation of the amplifier.
· A rear panel 12 volt auxiliary output jack provides up to
200 mA at 12 Vdc for accessories such as the
ART-15 Antenna Tuner.
· A step-start circuit limits the inrush current to the
power supply and tube heater. This circuit extends
the life of the amplifier components.
