CAUTION:
FAILURE TO FOLLOW THE BELOW STEPS WILL RESULT IN DAMAGE TO THE AMPLIFIER OR OTHER STATION EQUIPMENT.
• ALWAYS keep the air intake at the top of the amplifier clear. Maintain a spacing of at least 3/4” above the fan guards.
• ALWAYS keep the air intake on the bottom of the amplifier clear and free from obstructions. The rubber feet are about
3/4” high—maintain at least that clearance from objects below.
• DO NOT exceed 50W drive level as sever damage may occur. Driving the amplifier with more than 50W WILL NOT
increase output and will draw excessive current and overheat the amplifier.
• DO NOT run a power supply with more than 52 VDC output. If adjustment is possible run the power supply at 50 VDC.
All circuits have been optimized at this voltage.
• ALWAYS run the amplifier with the top cover and bottom cover installed. The top cover provides cooling to the alumi-
num finned head sink. The bottom cover shields the control board from stray RF and the bottom fan provides necessary
cooling to the tank circuit components. The control circuitry WILL fail to operate properly if ALL of the bottom cover
screws are not properly installed.
