5.16 VHF 5Watt Power Amplifier (12-004902)
5.16.1 Description
The power amplifier used is a triple stage solid-state low-noise amplifier. Class AB circuitry
is used in the unit to ensure good linearity over a wide dynamic range. The three active
devices are very moderately rated to provide a long trouble-free working life. There are no
adjustments on this amplifier, and in the unlikely event of failure then the entire amplifier
should be replaced.
