The PSL 1000 Power Supply generates over 2000 volts Direct Current at a current capacity of over.6000 amperes. It also generates 350 Volts Direct Current at .150 amperes. Both voltages are Lethal and will cause death upon contact with the human body. Although there are several built-in safety features to protect YOU from exposure to high voltage, the following steps whould be followed at all times. NEVER OPERATE, EITHER THE PLA 800 OR PSL 1000, REMOVED FROM THEIR INDIVIDUAL ENCLOSURES. NEVER REMOVE ANY CONNECTORS FROM EITHER UNIT WHILE POWER IS APPLIED. NEVER INSERT METAL OBJECTS INTO THE COOLING VENT HOLES ON TOP OR BELOW EITHER UNIT, WHILE POWER IS APPLIED. WARNING THE VOLTAGES USED IN THIS EQUIPMENT ARE SUFFICIENTLY HIGH TO ENDANGER LIFE. ALL PERSONNEL ARE ADVISED TO BE THOROUGHLY FAMILIAR WITH THESE UNITS BEFORE TROUBLESHOOTING THEM IN A POWER-ON CONDITION. ALWAYS USE CAUTION. INTRODUCTION The PLA-800 Linear Amplifier uses a pair of 4CX250’s tetrodes as final amplifier tubes. These tubes have been used and are still used today by the military because of its compact size and ability to put out power ina compact space. They also have the ability to amplify signal from .1 MHz to 500 MHz. Therefore their power bandwidth is approximately 500 MHz. The 4CX250B’s have a control screen grid. The voltage and regulated current for the screens are supplied by the PSL 1000 Power Supply. Using screen voltage regulation, the grids have the advantage of self-limiting the current flow to the plates of the tubes. As a result, the tubes cannot be driven into saturation causing distortion. The maximum allowable screen current is regulated by the power supply. Once that point of current demand is reached, the screen limits the plate current flow to it’s maximum. Therefore, and ALC circuit, to prevent driver overload, is not required. The maximum plate and cathode current flow is measured by the 0-500 ma. meter on the front panel. The screen current only, is measured by the 0-50 ma. meter located also on the front panel. The band switch and plate and loading capacitors are also located on the front panel. The capacitors use a 6:1 vernier ball drive to give smooth, easy tuning. Also located on the front panel are the two lights indicating filament voltage on and plate current on. The filament supply is contained in the PLA-800 and is protected by the 3 AG fuse next to the indicator light. These bulbs are tungsten elements, with a life of 50,000 hours. The plate on and off switch is located in the middle of both lamps. Both the amplifier and power supply are inter-locked for your safety. The removal of the FOUR (4) thumbscrews will allow you to slide the units forward and out of their respective enclosures. NEVER open either unit with the AC and DC power applied. As an added safety feature, the power supply has a mechanical shorting rod, which, upon sliding the unit out of the enclosure beyond 1/4 of an inch, will ground the high voltage capacitor bank. This is done for your safety and should NOT be defeated. Built into the PSL 1000 power supply is a maximum current overload circuit. If more than 600 ma. is delivered to the load, the circuit will activate, opening the plate relay and removing the high voltage. At the same time, the current overload indicator lamp on the front panel of the power supply will light and an audible alarm will sound. To reset the high voltage back, simply push the reset button on the panel. The power supply is also equipped with a voltmeter allowing you to monitor the high voltage (0-500 vdc) and the screen voltage (0-500 vdc). Under normal loading conditions, the PLA-800 will deliver 600 watts key down or 1200 watts PEP output. However, the key down power level should not be maintained for more than 10 seconds. In cases where RTTY or AM is used, the amplifier should be operated at one-half power level. 1200 watts PEP can be operated at any time. Tuning Procedure On the rear panel of the PLA-800 you will see the Power Output Connector or RF Out (SO239), a High Voltage connector, a Control Voltage Connector, a Push-to-Talk jack, a Ground Connector, and the Power Input Connector (SO239) or RF In. Connect the Control Voltage Connector and High Voltage Connector between the amplifier and power supply. The power supply has the appropriate mating connectors along with the AC input power plug. The AC input power can be adapted to 115 VAC or 230 VAC service (See power change over section). Apply the RF in coax connector from your transceiver. A transceiver with a variable output control should be used. That is, one which can vary the amount of drive power to the amplifier. Set your drive control on the transceiver to minimum. Connect the PTT (push-to-talk) connection using the RCA jack to your transceiver. This will put the amplifier into the circuit when you transmit from your transceiver. In the receive mode, the amplifier will be in by-pass. Connect a coax line from the RF OUT to your tuner or directly into your antenna load. An output power watt meter should be used, in-line with the antenna. This should be used to tune the amplifier correctly. Upon completion of the above, double check all connections to make sure they are installed correctly and tightly. Apply AC power by switching on the Main Power Switch on the power supply front panel. The green indicator light will illuminate and the yellow filament light…
