Amplifier Research - KAA2026 - 125 Watts, 700 kHz - 3 MHz, RF Amplifier, 19" Rack Mount
Construction of this model is in a 5¼-inch high cabinet, 16 inches deep, exclusive of handles, and 10.5 inches wide, with mounting flanges. Input and output connectors are located on the front. Forced-air cooling.
Protection against excessive heat rise of the amplifier module heatsink is by a temperature-sensing switch that interrupts the gate bias supply to the amplifier devices when activated. Operation resumes automatically when temperature has returned to normal operating temperature.
