[. . . ] Fuse: Type SFE; 234VAC and 200VAC operation: 15 Amp; 117VAC operation: 30 Amp. 5 UNPACKING INSTRUCTIONS Carefully remove your Commander II from its shipping carton making sure there is no damage evident from shipping. If there is any damage, notify the delivering shipper immediately, fully describing the damage. Do not destroy the packing material, since it may be reusable later, should you require factory service, or need to transport the Amplifier for any other reason. TRANSFORMER INSTALLATION Due to its weight, the power transformer is shipped separately to prevent damage to the amplifier cabinet, and it must be installed by purchaser. In order to install the HV transformer, both the top and bottom covers amplifier covers must be removed. [. . . ] Never operate the amplifier with more drive than required to produce the rated output for the operating mode used. Never cover the top of the amplifier cabinet with books, papers or other equipment as OVERHEATING MAY RESULT. · · · · · · IF ANY SITUATION YOU ARE NOT SURE ABOUT OCCURS, PLEASE CONTACT MANUFACTURER FOR ASSISTANCE.

Operation at the full rated output should not be attempted unless this line is capable of supplying at least 15 amps of peak current. It is strongly recommended that you operate this amplifier from a 234VAC line. The amplifier may be operated from a 117VAC power source capable of supplying at least 30 Amperes. To configure the amplifier for 117VAC or 200VAC operation, remove the voltage selection jumper cover on the rear panel of the amplifier and install appropriate jumpers (see illustration below). BE SURE YOU HAVE REMOVED THE LINE CORD PLUG FROM YOUR WALL SOCKET BEFORE REMOVING THE JUMPER COVER. IF YOU FAIL TO UNPLUG YOUR AMPLIFIER, YOU WILL EXPOSE YOURSELF TO LETHAL VOLTAGES. Install an appropriate plug on the power cord to mate with your wall receptacle. If you change the operating voltage as described above, be sure to install the proper fuse. The fuse is a type SFE, 15 Amp for 234 VAC & 200 VAC operation, 30 Amp for 117 VAC operation All Commander II amplifiers manufactured for export are wired for 200 or 234VAC, 50 or 60 Hz, depending on the final destination. Location of your Commander II requires that no equipment be placed directly above it, as air expelled from the tube exhaust can become quite hot. Allow at least 3 inches clearance on either side of the unit and between other equipment. Extending the tilt bail located on the bottom of the chassis improves the cooling airflow. To switch from transmit to receive the Commander II requires a contact closure or keying circuit capable of sinking 55ma of positive voltage (12 VDC open circuit) to ground. This connection is made to the RCA jack on the rear panel marked RELAY. Read the manual that came with your transceiver to determine the proper external connections. On some transceivers, this is not provided, and an alternate circuit will be required. Connect a good quality thruline Wattmeter between the amplifier output jack and the antenna or dummy load using RG8 or better coax. Connect the exciter (transceiver) RF output to the amplifier input using 50 ohm coax. Connect a ground lead, as short as possible, from earth ground to the Commander II's rear panel ground terminal. 11 OPERATING PROCEDURE After reading this manual and completing the Installation/Preparation Instructions, position the Commander II front panel controls as follows: · · · · · · ON/OFF -- OFF OPERATE/SSTANDBY -- STANDBY MULTIMETER SWITCH -- Vp (PLATE VOLTAGE) INPUT -- CENTER ON SCALE LOAD -- MINIMUM (COUNTER-CLOCKWISE) TUNE -- LEAVE AT FACTORY SETTING (NOTE: the TUNE control is a multi-turn piston capacitor and was factory preset for operation at 144. 200 MHz. See page 13 for more information. ) After presetting these controls, switch the ON/OFF switch to the ON position. [. . . ] If you use the Commander II mainly for CW and SSB, and after having tuned the unit to your antenna, you will be able to QSY up or down the CW/SSB band segment without making any tuning adjustments. Unless someone changes these adjustments, it will not be necessary to retune the amplifier each time you operate it. Just turn the unit on, wait for the green light and begin transmitting. If you decide later to operate in the FM portion of the band, it is best done by tracking up the band about 500 KHz at a time. [. . . ]
