16. MAINTENANCE
The Expert 1K-FA linear amplifier doesn’t need internal maintenance because it has a
cover without ventilation holes. No tube-type EHT is used so the high voltages present
in tube amplifiers, which sometimes attract dirt, are not present.
The user has only to periodically check the cleaning of the air filter on the front panel.
The frequency of such operation depends how dusty the amplifier location is and how
much it is used. We recommend monthly cleaning of the filter.
To clean the filter
a) Remove the front grid.
b) Remove the filter and clean it with care.
c) Reassemble the filter and the grid after having carefullly cleaned the
mechanical structure that includes them.
Note: check the filter if an unexpected rise of temperature is noticed.
Note: never operate without the filter, as dust could be deposited on the surface of the
heatsink limiting its ability to cool.
Note:
to allow the most efficient heat-dissipation, large copper parts have been used.
