The AMERITRON AL-572 gives you

1300 Watts PEP SSB nominal power output

on 160 through 15 Meters, using four

rugged 572B tubes with 3 second warm-up

time. This whisper quiet, desktop linear

plugs into your 120 VAC outlet - no spe-

cial wiring needed.

Yo u get heavy duty

power supply; fully neutral-

ized tubes; pressurized venti-

lation; multi-voltage power transformer;

front panel ALC control; 6:1 vernier drives

... and more!

You'll typically get 1300 Watts PEP

SSB, 1000 Watts CW continuous, on all

amateur bands from 160 through 15 Meters

AMERITRON's exclusive

Instantaneous RF Bias

completely turns

off the 572B tubes between words and dots

and dashes, for cooler operation and longer

component life, while Dynamic ALC

can

more than double your average SSB power.

AMERITRON's Step-Start

Inrush

Protection limits inrush current to your

power supply and tube filament, greatly

extending tube life and amplifier compo-

nents.

A heavy duty power supply using a

high silicon steel transformer delivers 2500

Volts at 0.7 Amps with good regulation.

A Pi-Network tuned input using slug

tuned coils provides a good 50 ohm load

for your rig. A quiet internal fan draws in

cool air over power supply components and

pressurizes the tube compartment.

Grid current, plate current and forward

PEP output power are continuously moni-

tored by dual, lighted cross-needle meters.

A fourth scale switches among peak

reflected power (and SWR), high voltage,

ALC threshold, and ALC output voltage.

Ameritron’s multi-voltage power trans-

former has a unique buck-boost winding.

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 perform-

ance and long component life -- regardless

of your line voltage.

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 accessory jackp; 12

VDC keying relay for solid state/tube rigs;

tough, nearly indestructable Lexan-over-

aluminum front panel. Shipped with trans-

former installed. Draws 16 A at 120 VAC.

For lightning fast QSK operation use

the optional Ameritron electronic PIN

diode QSK switch. Shipped wired for 120

VAC. Weighs 40 lb. Power required: 120

VAC, 16 amps. Made in the USA.

Ameritron’s compact

AL-800 /AL-800H amps

are both desktop linears

with plenty of muscle!

At 14.25Wx8.5H

x14.5D inches, the more

compact AL-800 uses a

single 3CX800A7 to pro-

vide 1250 Watts PEP SSB

and 850 Watts CW with 85

Watts typical drive level.

And the AL-800 will

even run from a 20-Amp

120 VAC line source if

desired. AL-800 typically

draws 17 Amps peak cur-

rent at 120VAC, or 8 Amps

at 240 VAC and weighs just 51 lbs.

For more power and headroom, the AL-

800H uses a pair of 3CX800A7 tubes to

easily provide 1500 Watts PEP/CW with a

typical drive level of just 55 Watts.

The AL-800H draws 14 Amps peak cur-

rent at 240 VAC (1500 Watts CW output)

and weighs just 52 lbs.

Other than power differences, these

amplifiers are very similar in features and

operation. Both cover 160-15 Meters, and

are modifiable to cover 12/10 M with proof

of your FCC license.

Both include a Step-Start

input power

circuit, a time delay circuit to allow for tube

warm-up, thermal overload protection, grid

current limiting to protect your tube(s), a

DynamicBias

circuit and a built-in multi-

voltage (14 user-selectable AC line voltages

from 90-140; 200-250 VAC) heavy duty

power transformer. Hefty 32 lb. grain orien-

tated silicone steel core transformer.

Front panel monitoring and tuning func-

tions are also virtually identical. Both

amplifiers include a Standby/Operate switch

for barefoot or full power operation, an ALC

SET control, Transmit and Fault LEDs.

Dual LED illuminated Cross-Needle

meters provide detailed monitoring of

amplifier performance. The left meter con-

tinuously measures grid and plate currents,

and the right meter continuously measures

peak RF output power on one scale, and

plate voltage, Reflected power and SWR,

ALC voltage, and ALC adjustment set.

Quiet pressurized ventilation keeps tubes

safely cooled. A Pi/Pi-L output network

gives you smooth tuning and wide matching

range. Vernier reduction drives make tuning

and loading adjustments smooth and easy.
