AMERITRON Doubles Average SSB Power

Ameritron’s AL-80B

kilowatt output desktop

linear can double your

average SSB power out-

put with high-level RF

processing using

Ameritron’s exclusive Dynamic ALC

Yo u get cooler operation because the

AL-80B’s exclusive Instantaneous RF

Bias

completely turns off the classic 3-

500 tube between words. It saves hun-

dreds of watts wasted as heat.

Yo u get a full kilowatt PEP output

from a whisper quiet desktop linear. It’s

a compact 8

/2Hx14Dx15

/2 inches and

plugs into your nearest 120 VAC outlet.

Covers all bands 160-15 Meters, includ-

ing WARC and MARS (10/12 Meters

modifiable; FCC license required).

Yo u get 800 watts output on CW, 500 watts

output on RTTY, an extra heavy duty power

supply, genuine 3-500 tube, nearly 70% effi-

ciency, tuned input, Pi/Pi-L output, inrush cur-

rent protection, multi-voltage transformer, dual

cross-needle meters, QSK compatability, two-

year warranty, made in the USA, plus much

more!

Dynamic ALC

doubles average SSB power

The AL-80B’s exclusive Dynamic ALC

gives you high-level low-distortion RF pro-

cessing. It can more than double your average

SSB power for up to 6 dB improvement in

intelligibility, maximizing talk power without

distortion/splatter.

A convenient front panel control lets you

adjust output power level.

The AL-80B’s exclusive Instantaneous RF

Bias

turns off the classic 3-500 tube (except

filaments) between words and dots and dashes,

elininating hundreds of watts wasted as heat

for cooler operation and longer component life.

The guts of the AL-80B is its heavy duty

power supply. A 26 pound transformer using a

high silicone steel core, computer grade capac-

itors, heavy duty bleeders and ten 3 amp, 1000

volt power rectifiers give you a stiff 2700 volts

fully loaded. Many amps using two 3-500s use

such small power supplies they don’t deliver

much more power output than the AL-80B.

The AL-80B is built on a rugged steel

chassis with a separate fully-shielded RF com-

partment to minimize RFI and TVI.

A whisper quiet internal fan draws in cool

air over power supply components and pressur-

izes the classic 3-500 tube compartment to

remove heat for longest life.

Tuned input lets your rig deliver full output

50 Ohm broadband Pi-Network tuned input

is used. Even fussy solid state transmitters

will deliver full power!

A carefully designed Pi/Pi-L output net-

work using the optimum Q for each band gives

exceptionally smooth tuning, extremely wide

matching range, full band coverage, and peak

performance at all power levels.

Step-Start Inrush

Protection

stops damaging

inrush current with a start up

sequence that’s easy on your

tube and power supply compo-

nents.

Our exclusive Multi-Voltage

Power Transformer

lets you

optimize for 14 different pri-

mary line voltages. The high

voltage secondary can be wired

to reduce plate voltage for effi-

cient operation below 400 watts

for use outside the USA.

AMERITRON’s dual LED

illuminated cross-needle meters

give you four separate meters to

monitor your operating conditions -- you can

tell right away if something is wrong. Grid and

plate current and forward output power are

monitored for improper loading and abnormal

conditions.

The fourth meter can be switched to moni-

tor your 3-500 tube DC plate voltage, reflected

PEP power, antenna system SWR, ALC volt-

age to your rig, and the grid current that starts

ALC action -- get a clear picture of your AL-

80B.

The T/R (transmit/ receive) relay in the

AL-80B switches nearly as fast as some vacu-

um relay QSK T/R switches.

Operate/Standby switch lets you run bare-

foot, but can instantly switch to full power if

needed.

Has transmit LED; 12 VDC, 200 mA

accessory jack; 12 VDC keying relay for solid

state and tube rigs; tough Lexan over-alu-

minum front panel. Two-year waranty.

Weighs 48 lb. Power required: 120 VAC,

12A. Made in the U.S.A.
