Two bias settings allow either high efficiency RTTY and CW operation at 1500 watts of output at nearly 70% plate efficiency or low distortion 1500 watts PEP, SSB or SSTV output. Silver plated tank components provide high efficiency operation above 20 meters. The Pi-L tank circuit permits full impedance matching capability over the entire 160 meter band. The tuning capacitors and bandswitch have a 35% safety factor to virtually eliminate tank circuit component failures, even under adverse operating conditions.\u003c\/p\u003e\n\u003cp\u003eThe cooling system keeps the components and tube safely below the manufacturers ratings, even while operating at 1500 watts output with a steady carrier. The filament supply has inrush current limiting to insure maximum tube life. Shielding and by-passing help prevent TVI and RFI at the high power levels in the AL-82.\u003c\/p\u003e\n\u003cp\u003eThe AL-82 has two illuminated meters. One is the Grid Current Meter that provides a continuous reading of the 3-500ZG grid current. This is an Ameritron first. Grid current indicates proper amplifier performance better than any other parameter. The other is a multi-meter that displays plate voltage, plate current, peak R.F. output power and drive power\/ALC detector voltage. Some competing amplifiers using two 3-500ZGs cant deliver as much power as the AL-82. Why? Because the lightweight power supplies they use dont deliver enough high voltage to permit use of the full capability of the two 3-500ZGs. The AL-82 corrects this problem while still keeping the price at a reasonable level. The power supply in the AL-82 has a commercial service rated 32 pound tape wound Hypersil transformer and heavy duty rectifiers in a full wave bridge circuit with computer grade capacitors. No load voltage is 3600 V; full load voltage 3300V -- better than most competing dual 3-500ZG amplifiers.\u003c\/p\u003e\n\u003cp\u003eExamine the features and component ratings of the AL-82 is a well engineered amplifier, built to give you years of power house service.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAL-82 Specifications:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eFrequency coverage\u003c\/b\u003e: 1.8, 3.5, 7, 14, 21 MHz and WARC bands.
