AMERITRON Doubles Average SSB Power Ameritrons AL-80B kilowatt output desktop linear can double your average SSB power output with high-level RF processing using Ameritrons exclusive Dynamic ALC TM. You get cooler operation because the AL-80Bs exclusive Instantaneous RF Bias TM completely turns off the classic 3- 500 tube between words. It saves hundreds of watts wasted as heat. You get a full kilowatt PEP output from a whisper quiet desktop linear. Its a compact 8 1/2Hx14Dx15 1/2 inches and plugs into your nearest 120 VAC outlet. Covers all bands 160-15 Meters, including WARC and MARS (10/12 Meters modifiable; FCC license required). You get 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 compatability, twoyear warranty, made in the USA, plus much more! Dynamic ALC TM doubles average SSB power The AL-80Bs exclusive Dynamic ALC TM gives you high-level low-distortion RF processing. 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-80Bs exclusive Instantaneous RF Bias TM 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 capacitors, 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 dont 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 compartment to minimize RFI and TVI. A whisper quiet internal fan draws in cool air over power supply components and pressurizes 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 network 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 TM stops damaging inrush current with a start up sequence thats easy on your tube and power supply components. Our exclusive Multi-Voltage Power Transformer TM lets you optimize for 14 different primary line voltages. The high voltage secondary can be wired to reduce plate voltage for efficient operation below 400 watts for use outside the USA. AMERITRONs 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 and plate current and forward output power are monitored for improper loading and abnormal conditions. The fourth meter can be switched to monitor your 3-500 tube DC plate voltage, reflected PEP power, antenna system SWR, ALC voltage 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 vacuum relay QSK T/R switches. Operate/Standby switch lets you run barefoot, 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-aluminum front panel. Two-year waranty. Weighs 48 lb. Power required: 120 VAC, 12A. Made in the U.S.A. AL-80B $1399 Suggested Retail 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 special wiring needed. You get heavy duty power supply; fully neutralized tubes; pressurized ventilation; 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, greatly extending tube life. 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 monitored by dual, lighted cross-needle meters. A fourth scale switches among peak reflected power (and SWR), high voltage, ALC threshold, and ALC output voltage. 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. Output power: 1250 watts PEP, single 3CX800A7. 1500 W plus, two 3CX800A7s. 160-15 Meters including WARC bands. Modifiable for 12/10 Meters, FCC license required.
