5.1.5 5Watt Power Amplifier (12-001801)
5.1.5.1 Description
The power amplifier fitted to this unit is a multi-stage, solid state class A power
amplifier. All the semi-conductor devices are very conservatively rated to ensure low
device junction temperatures and a long, trouble free working lifetime.
The power amplifier should require no maintenance over its operating life. Under no
circumstances should the cover be removed or the side adjustments disturbed unless it is
certain that the amplifier has failed; since it is critically aligned during manufacture and
any re-alignment will require extensive test equipment.
