Legal Limit

amplifiers give you

nearly full legal SSB power output

for 65% of the price of a full legal

limit amplifier . . . and no one will

ever know the difference!

You get 1300 Watts PEP SSB

nominal power out on amateur

bands 160 - 15 M.

Four rugged 572B tubes give

you near legal limit power and

instant 3 second warm-up time.

This whisper quiet, desktop lin-

Four rugged 572B Tubes

The AL-572 uses four rugged fully neu-

tralized 572B tubes. Each tube has a heavy

duty Graphite Anode, low loss white

Ceramic Base, superior Titanium Getter

and legendary quality and ruggedness.

Ameritron’s exclusive ParasiticKiller

effectively suppresses all parasitic oscilla-

tions.

Near Legal Limit

Power Output

You’ll typically get 1300 Watts PEP

SSB, 1000 Watts CW continuous, 1000

Watts 1/2 hour PEP two-tone test on all

amateur bands from 160 through 15 Meters

(WARC bands and 10 Meters with reduced

performance — user modified for 10/12

Meters with license).

Instantaneous RF Bias

eliminates heat

Ameritron’s exclusive Instantaneous RF

Bias

completely turns off the 572B tubes

between words and dots and dashes. It

eliminates hundreds of watts wasted as heat

to give you cooler operation and longer

component life.

DynamicALC

doubles average SSB power

Ameritron’s exclusive Dynamic ALC

gives you high level, low distortion RF

processing. It can more than double your

average SSB power.

Front panel control lets you adjust out-

put power.

Heavy duty Power Supply

A heavy duty power supply using a high

silicon steel transformer delivers 2500 volts

at 0.7 amps with good regulation.

The plate supply uses a full wave dou-

bler, 200 amp peak surge current diodes, 7

watt, 50 K ohm wire wound bleeder resis-

tors and a bank of high quality computer

grade capacitors totaling 26 ufd.

Step-Start Inrush Protection

When you turn on your amplifier, a

massive inrush current flows. Eventually

this current will damage your amplifier.

Ameritron’s Step-Start Inrush

Protection

limits damaging inrush current

to your power supply and tube filament.

This greatly extends the life of your ampli-

fier components and tubes.

Pi/Pi-L Output Network

The AL-572 Pi/Pi-L output network

gives you exceptionally smooth tuning,

wide matching range, full band coverage

and peak performance at all power levels.

Ball bearing vernier reduction drives on

plate and load controls make tuning precise

and easy. Detailed logging scales let you

quickly return to your favorite frequency.

Tuned Input lets your rig

deliver full output

A Pi-Network tuned input using slug

tuned coils provides a good 50 ohm load

for your rig. Even the fussiest solid state

rig will deliver full power to your AL-572.

Whisper Quiet pressurized cooling

A whisper quiet internal fan draws in

cool air over power supply components and

pressurizes the tube compartment to

remove heat for longest life.

Two lighted Cross-Needle Meters

Grid current, plate current and forward

PEP output power are continuously moni-

tored to tell you of improper loading and

abnormal conditions.

A fourth scale switches among peak

reflected power (and SWR), high voltage,

ALC threshold and ALC output voltage.

Multi-Voltage Power Transformer

Ameritron’s Multi-Voltage Power

Transformer has a unique buck-boost wind-

ing. It lets you select from 14 primary

voltages centered on 115 and 230 VAC.

Yo u can match your AL-572 to your AC

line voltage so you’ll get peak performance

and long component life — regardless of

your line voltage.

QSK Compatible

For lightning fast QSK operation use the

optional Ameritron electronic PIN diode

QSK switch. Use the external QSK unit,

QSK-5, $349, or install the internal QSK-

5PC board. Contact Ameritron.

Plus More!

An Operate/Standby switch lets you run

barefoot, but you can instantly switch to

full power if you need it.

Transmit LED; 12 VDC, 200 mA acces-

sory jack; 12 VDC keying relay for solid

state/tube rigs; tough, nearly indestructable

Lexan-over-aluminum front panel.
