The DenTron DTR 2000L Linear Amplifier is a conservatively designed 2000 Watt PEP 160 15 meter amplifier of unique design. Through years of designing linear amplifiers, DenTron Radio has greatly simplified the circuitry of the DTR-2000L, building in years of reliability based on the experience of our world-famous MLA-2500 series. The incorporation of a single 8877 (a tube till now used almost exclusively in broadcasting applications) makes the DTR 2000L a no-compromise unit featuring the most powerful final tube rating allowed under current FCC regulations . . . 1500 Watts plate dissipation! The DTR 2000L has been fully tested at the maximum legal Amateur power limit on all modes; SSB, CW, SSTV, RTTY, as well as under contest conditions. The unit covers all the Amateur Bands from 1.8 to 21.450 MHz, along with most MARS operating frequencies, without modifications. With factory modifications, the DTR-2000L will operate on any frequency from 1.8 to 35 MHz, strictly for commercial applications. A single 8877 external anode ceramic metal triode is used in the DTR-2000L, operating in grounded grid. A built-in continuous duty power supply completes the unit, capable of either 117V or 234V operation, although 234V line voltage is recommended. Cooling of the unit is accomplished through an EIMAC specified pressurized chamber and chimney. A vacuum impregnated power transformer, hi-lo power switching, dual meters for monitoring plate voltage and current, and modular construction complete the DTR-2000L package. Please be certain to completely read this manual before operating your new DTR 2000L. U. S. Amateur regulations limit the use of high powered amplifiers such as the DTR 2000L to licensees of General Class or higher.
