Ameritron AL-82
Ameritron`s Dual 3-500Z Amplifier
The Ameritron AL-82 Linear Amplifier is designed to give you years of trouble free service at the full legal output power limit.
An 1800 watt continuous commercial rated Hypersil transformer is standard with heavy duty rectifiers in a full wave bridge supply with computer capacitors. 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.
The 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.
The 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.
Examine the features and component ratings of the AL-82 is a well engineered amplifier, built to give you years of power house service.
