SECTION 7.0
MAINTENANCE AND SERVICING
7.1 PERIODIC MAINTENANCE
The only periodic maintenance required on the CW TWT amplifier system is insuring that the cooling
vents are not obstructed in such a manner that the air flow is restricted. Periodic cleaning of the vents
may be required depending on the degree of dust in the atmosphere.
7.2. SERVICING THE AMPLIFIER
Servicing of the amplifier by the operator is not recommended. Most of the internal circuitry requires
special and unique test instruments to trouble shoot, align and calibrate the circuits. Should servicing be
required, refer to Paragraph 7.3.
