CARE AND CLEANING
Caution!
• ALWAYS switch the preamplifier off and disconnect it from the
mains supply before attempting to clean it.
• NEVER apply cleaning products directly to the preamplifier as
they may enter the unit and cause damage.
• NEVER use any of the following cleaning products as they may
damage the finish:
• Wax polish
• Spirit or alcohol based cleaners
• Corrosive or abrasive cleaners
In most cases wiping the units with a slightly damp soft cloth will give
satisfactory results. Non-abrasive glass cleaners containing ammonia or
vinegar, applied with a soft cloth may also be used. If you have concerns
about the suitably of a cleaner, first try it out on a part of the unit that is less
visible, such as the rear panel.
MAINS FUSE
The mains fuse is located inside the mains input receptacle on the power supply rear
panel. If you suspect that the fuse has blown, follow the procedure below:
• Disconnect the preamplifier from the mains supply.
• Insert a small screwdriver into the recess in the fuse cover as
shown in the diagram below and carefully lever the cover up.

• Check the fuse with a continuity tester and replace any blown
fuses with one of the rating and type shown below. Using a fuse
of the incorrect type or rating may create a safety hazard or
cause damage to the unit and may also result in the warranty
being voided.
