Feel the need for maxi-

mum legal HF output

power? AMERITRON’s

AL-1500 will give it to you.

Using the Herculean

3CX1500A/ 8877 ceramic

tube with its high power

gain, the AL-1500 needs

only 65 watts of drive from your exciter to

deliver the goods-- transceivers and other

exciters just loaf at 1500 watts out.

Cool, efficient operation is provided by a

forced-air system with tube chimney, using

a commercial grade die-cast ball bearing

blower for maximum tube life. The tube is

further protected by time delay starting and

automatic over-current shutoff to remove

drive power if the amplifier is mis-tuned.

Yo u get full legal power output from a

whisper quiet desktop linear. Measures

/2D x17Wx10H inches, and covers all

bands, 160-15 Meters, including WARC and

MARS (80% of full output set to nearest

amateur band). 10/12 Meters

modifiable.

Yo u get 1500 watts out-

put (1/2 hour continuous

carrier) and 2500 watts

(30 second continuous

carrier and 2500

watts- plus 30

minute PEP two-

tone test). You get

all this power, plus, 65% efficiency, pi-net-

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

rent protection, multi-voltage transformer,

QSK compatability, and a one-year warranty.

The guts of the AL-1500 is its heavy duty

power supply, with a 32 lb. Hypersil

(R)

transformer using a high silicone steel core,

computer grade capacitors (33 mfd total),

heavy duty bleeders and twenty 3 amp,

1000 volt power rectifiers give you a stiff

3300 volts fully loaded.

The AL-1500 is built on a rugged steel

chassis with a separate RF compartment

fully shielded to keep RF from leaking out,

keeping RFI and TVI to a minimum.

Superb RF design and layout, Hi-Q tank

circuit and commercially rated RF power

components give you 65% plate efficiency

over the entire operating range. Power goes

into the antenna instead of into heat.

50-ohm broadband Pi-Network tuned in-

put with slug-tuned coils is used. Even fussy

solid state transmitters deliver full power!

A carefully designed Pi/Pi-L output net-

work using the optimum Q for each band

with vernier ball drives gives smooth tuning,

wide matching range, full band coverage,

and peak performance at all power levels.

The AL-1500’s grid overload circuit pro-

tects the tube from excessive grid current; if

175 mA of peak gric current is reached, the

“OPR” LED will no longer light and the

amplifier will go into a bypass condition

until reset by the operator.

Transformer provides many options

Since excessive line voltage stresses

components (low line voltage causes a “soft

tube” effect, for example), Ameritron’s

exclusive Multi-Voltage Power

Transformer

lets you optimize for different

line voltages. Select from 4 different primary

voltage ranges, from 205-219 VAC to 252 to

265 VAC. The amplifier comes wired from

the factory for 240 VAC.

The AL-1500 has two illuminated panel

meters. Grid Current meter provides contin-

uous reading of the critical grid current and

indicates proper, safe amplifier operation.

The other meter can be selected to read

Plate Voltage, Plate Current, Peak RF

Watts, or ALC. A SSB/CW selector switch

chooses bias voltage for best linearity on

SSB or lowest dissipation on CW.

The Operate/Standby switch, in Standby,

maintains the tube’s filament and plate volt-

ages while allowing “barefoot” operation.

Includes 12 volt DC auxiliary jack and

an “XMT” LED to provide indication of

proper amplifier keying by the exciter.

Power required: 240 VAC, 15 amps.

Frequency coverage:

1.8,3.5,7,14, 21 MHz

& Warc bands. User-

modifiable for 28 MHz

(FCC license required).

Ameritron’s Dual 3-500Z Amplifier

Ham Radio’s toughest

tube -- the Eimac

(R)

3CX1200Z7 is in ham

radio’s toughest amplifier! It

has a 50-Watt control grid

dissipation. It also has the

same super heavy duty

power supply that’s in our

AL-1500 amplifier that

loafs at full power. A

3CX1200Z7 has the

lowest quantity history

of field replacement of any modern

transmitting tube that we use. It has

the ruggedness and power handling of

ceramic tubes combined with the long-

life of thoriated tungsten filaments.

This classic linear gives you

full legal output using a pair of

3-500Z graphite tubes. Examine

the features and component rat-

ings of the AL-82 and compare

it to any competing amplifier

using two 3-500Zs. Most com-

peting

ampli-

fiers using 3-500Zs can’t

give you 1500 Watts because

their lightweight power sup-

plies can’t use these tubes to

their full potential. Our AL-82 amplifier

uses the same Hypersil

(R)

power trans-

former and used in the AL-1500 and AL-

1200 amplifiers -- powerful stuff, just

loafs at full power!
