Ameritron's legendary AL-80A kilowatt amplifier has been completely redesigned and extensively improved. The all New AL-80B kilowatt output desktop linear can double your average SSB power output with high-level RF processing using
Ameritron's exclusive Dynamic ALC. You get cooler operation because the AL-80B's exclusive Instantaneous RF Bias completely turns off the 3-500ZG tube between words. It saves hundreds of watts wasted as heat.

You get up to a full kilowatt PEP output from a whisper quiet desktop linear. It's a compact 8.5"Hx15.5"Dx14.5"W and plugs into your nearest 120VAC outlet. Covers all bands 160-15 meters, including WARC and MARS (user modified for 10/12
meters with license). You get up to 1000 watts output on SSB, 800 watts output on CW, 500 watts output on RTTY, an extra heavy duty power supply, genuine 3-500 tube, nearly 70% efficiency, tuned input, Pi/Pi-L output, inrush current
protection, multi-voltage transformer, dual Cross-Needle meters, QSK compatibility, Two Year Warranty, Made in USA, plus much more.

Dynamic ALC doubles average SSB power
The AL-80B's exclusive Dynamic ALC gives you high-level low-distortion RF processing. When activated, it can more than double your average SSB power and produce up to 6 dB improvement in intelligibility. It maximizes your talk power without
distortion and splatter. A convenient front panel control lets you adjust your output power level.

Instantaneous RF Bias eliminates heat
The AL-80B's exclusive Instantaneous RF Bias completely turns off the 3-500 tube (except filaments) between words and dots and dashes. it eliminates hundreds of watts wasted as heat to give you cooler operation and longer component life.

Guts Heavy-Duty Power Supply
The guts of the AL-80B is its heavy duty power supply. A 26 pound transformer using a high silicone steel core, computer grade capacitors, heavy duty bleeders and ten 3 amp, 1000 V power rectifiers give you a stiff 2700 volts fully loaded.
Many amplifiers using two 3-500s use such small power supplies they don't deliver much more power output than the AL-80B.

Genuine 3-500ZG Tube
The AL-80B uses a genuine 3-500ZG tube warranted by the manufacturer -- not cheaper, less reliable 3-500s used by some competitors.

70% efficiency
The AL-80B is built on a rugged steel chassis. It has a separate RF compartment that's fully shielded to keep RF from leaking out. This keeps RFI and TVI to a minimum. Superb RF design and layout, Hi-Q tank circuit and commercially rated RF
power components give you nearly 70% plate efficiency over most of the amateur bands. You power goes into your antenna instead of heating up your amplifier. A whisper quiet internal fan draws in cool air over power supply components and
pressurizes the 3-500 tube compartment to remove heat for longest life.

Tuned Input lets your rig deliver full output
A 50 ohm broadband Pi-Network tuned input is used. Even the fussiest solid state transmitter will deliver full power to your AL-80B. Low loss slug tuned coils -- tunable from the rear panel -- let you optimize performance.

Pi/Pi-L Output Network
A carefully designed Pi/Pi-L output network using the optimum Q for each band gives you exceptionally smooth tuning, extremely wide matching range, full band coverage and peak performance at all power levels. Ball bearing venier reduction
drives with logging scales on both the plate and load controls make tuning precise and easy. It also lets you rapidly retune to your favorite frequency.

Step-Start Inrush Protection
When you first turn on your amplifier, a massive inrush current flows. Your house lights flicker as you hear a load "thump" from your amplifier. This terrible inrush current stresses all your power supply components to their limits. Your
cold tube filament suffers abusive thermal shock. Eventually, this massive inrush current will damage your amplifier. The AL-80B special Step-Start Inrush Protection stop damaging inrush current. By starting your AL-80B through a 10 ohm
current limiting resistor, then shorting the resistor with a relay, the AL-80B gives you a start up sequence that's easy on your tube and power supply components.

Multi-Voltage Power Transformer
Excessive line voltage stresses components and causes them to wear out. Low line voltage causes a "soft-tube" effect -- low output and signal distortion. Ameritron's exclusive Multi-Voltage Power Transformer lets you optimize for different
line voltage. Select from 14 different primary voltages from 90 - 140 VAC and 205 to 250 VAC. The high voltage secondary can be wired to reduce plate voltage for efficient operation below 400 watts for use outside the USA.

Dual Illuminated Cross-Needle Meters
Ameritron's dual illuminated cross-needle meters give you four separate meters to monitor your operating conditions -- you can tell right away if something is wrong. Grid current, plate current and forward PEP output power are continuously
monitored to tell you of improper loading and abnormal conditions. The fourth meter can be switched to monitor you 3-500 tube DC plate voltage, reflected PEP power and the SWR of your antenna, ALC voltage to your rig and the grid current
that starts ALC action -- you get a clear operating picture of your AL-80B.

QSK Compatible
For lightning fast QSK operation use the optional Ameritron electronic PIN diode QSK switch. Get the external QSK switch (QSK-5) or the Internal Switch (QSK-5PC).

Plus More...
An Operate/Standby switch lets you run barefoot, but you can instantly switch to full power if you need it. Has transmit LED; 12 VDC, 200 mA accessory jack; 12 VDC keying relay for solid state and tube rigs; tough, nearly indestructible
Lexan front panel. Shipped with transformer installed and wired for 120 VAC. Draws 12 amps at 120 VAC.

Two Year Warranty: Twice the protection of our nearest competitor
No other kilowatt amplifier comes with a 2 year warranty. In the unlikely even that there are defects in materials or workmanship Ameritron will fix it free for 2 years -- other may give you a prorated warranty. The 3-500 tube is covered by
the tube manufacturer's warranty
