The all New AL-80B kilowatt output desktop linear can double your average SSB power output with high-level RF processing using Ameritrons exclusive Dynamic ALC. You get cooler operation because the AL-80Bs 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. Its a compact 8.5" x 15.5" x 14.5 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). Dynamic ALC doubles average SSB power. The AL-80Bs 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-80Bs 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. 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 dont deliver much more power output than the AL-80B. The AL-80B is built on a rugged steel chassis.
It has a separate RF compartment thats 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.
Or the Internal Switch QSK-5PC. 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. Draws 12 amps at 120 VAC.
