7.1
Safety Procedures
WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING
When the amplifier is operational with the rear panel removed, lethal voltages are easily
accessible.
Use properly insulated tools for any calibration work and do not make contact with any internal
components.
Ensure that all high voltage components have been grounded (use an earthing stick).
Ensure that power has been disconnected from the unit before any maintenance work is
started.
FIRST LEVEL OF MAINTENANCE
7.2
Routine Maintenance
The only routine maintenance required by the amplifier is periodic changing of the fan,
air filter and removal of accumulated dust from inside the tube cavity and from the air filter.
The periods between routine maintenance will depend upon operating conditions, ambient
temperature, ambient dust levels and humidity. It is advisable to carry out preventative checks
at 3 month intervals and to change fans at least every 18 months, or before if they become
noisy or show signs of wear.
Periodic replacement of the tube will also be necessary.
The operating life of the tube is very dependant upon operating conditions, for example: line
voltage fluctuations over ±5%, temperatures over +30°C, high humidity, the presence of dust
and incorrect calibration of the amplifier will all result in a greatly reduced tube life.
SECOND LEVEL OF MAINTENANCE
7.3
Replacement of Components
N.B. TO RE-ASSEMBLE THE UNIT, SIMPLY REVERSE THE SEQUENCE OF
OPERATIONS.
N.B. THE FOLLOWING PROCEDURE SHOULD ONLY BE CARRIED OUT BY QUALIFIED
PERSONNEL USING THE CORRECT TOOLS AND EQUIPMENT. UNQUALIFIED OR
INEXPERIENCED PERSONNEL NOT USING THE CORRECT TOOLS AND
EQUIPMENT CAN EASILY CAUSE DAMAGE TO THE UNIT WHICH WILL
IMMEDIATELY INVALIDATE THE GUARANTEE.
