CHAPTER 5
MAINTENANCE
5.1
SAFETY RULES
PAY ATTENTION ! PAY ATTENTION ! PAY ATTENTION ! PAY ATTENTION !
When the amplifier is working on, and the rear panel is been removed, inside of equipment
are present dangerous high tensions. Use isolated tools for any type of adjustment and don’t
touch any internal components of equipment when this is switched on. Verify that the
equipment internal high tensions are been short circuited (eventually use a switch hook).
Verify to disconnect the mains voltage of the amplifier before to execute any maintenance
operations.
MAINTENANCE FIRST LEVEL
5.2
SAFETY RULES
Only routine maintenance that is necessary for amplifier are the periodic checking of the
fans, the replacing of the air filter and the cleaning inside the tube cavity and the air filter.
The periodicity of this maintenance depends from the working conditions of equipment,
enviromental temperature, the dust level of the air, humidity. It’s advisable to execute a
preventive checking each three months and to replace the blowers that has some problems as
noise or friction. Then, at regular period, is necessary the replacing of the tube. The numbers
of the tube life hours depends from the working conditions, example: mains voltage with
variations greater than ± 5%, environmental temperature greater than 30°C, high humidity,
dust presence and not corrected adjustment of the amplifier, are the causing of high
reduction of the tube life.
MAINTENANCE SECOND LEVEL
5.3
MODULES REPLACING
NOTE: TO REMOUNTING THE MODULES EXECUTE THE PROCEDURE WITH INVERSE
SEQUENCE.
NOTE: THESE OPERATIONS MUST BE EXECUTED BY VERY QUALIFIED TECHNICIANS
AND EQUIPPED
WITH NECESSARY INSTRUMENTS.
UNCORRECTED OPERATIONS CAN CUASE A SERIOUS DAMAGE OF THE EQUIPMENT
AND CAUSE AUTOMATICALLY THE RESOLVING OF THE WARRANTY.
