The Amp Supply LK800A Linear Amplifier is a compact 1500 Watt output 160-15 meter Amplifier of modern design. It is a high performance piece of equipment requiring a minimum of maintenance through years of operation. The LK80GA was engineered conservatively, with American components and ingenuity. The unit is field-tested and rated for 3000 Watts PEP input continuous in SSB service and 2000 Watts CW input along with many MARS operating frequencies, without modifications. With the addition of the external power pac the LK-800Awill operate at 1500 watts continous output on CW, SSTV and RTTY. Three EIMAC 3CX-800A7 triodes are employed, operating in grounded grid in conjunction with a solid state power supply capable of either 117V or 234V operation. The LK800A uses a double duty cooling system which allows cooling of not only the tubes, but the Power Supply as well. Tuning the LK800A is a simple procedure, since the unit is designed for long-term stability in virtually any operating situation. Tuned input and standard relay switching circuitry makes the LK800A compatible with any solid state or tube Transceiver or Transmitter available. The LK800A, despite its straight-forward design and minimal user required adjustment, is nonetheless a sophisticated electronic instrument. Therefore, if the unit is operated outside the parameters outlined in this owner’s manual, it is possible that damage can result. Please read this manual carefully before putting your LK800A on the air.
