Descrizione: LINEAR POWER AMPLIFIER
Informazioni:
                                    The Ameritron AL-572 is a 1000 watt CW, 1300 watt PEP
(nominal output power) linear
amplifier that operates on all Amateur bands from 160
through 15 meters (WARC bands and ten
meters with reduced performance). The AL-572X and AL-572Y
are export models that operate
from 160 through 10 meters.
The AL-572 uses four 572B tubes in a class AB2 grounded grid
circuit. High-quality power
supply and RF components combine with an accurate
peak-detecting directional coupler, front
panel adjustable true ALC circuit, and automatic bias
switching to make this the best featured
and most reliable 572B amplifier available. The AL-572 and
AL-572Y are factory-wired for 120
volt, 50/60 Hz ac line voltage. The AL-572X is factory wired
for 240 volts. All models are easily
converted to other supply voltages between 90 and 250 volts ac.
