ENVIRONMENT
1) Water and Moisture. Do not use this product near water - i.e. near a bathtub, ash bowl,
kitchen sink or laundry tub; in a wet basement; or near a swimming pool or the like. Damp
basements should be avoided.
2) Heat. The product should be situated away from heat sources such as radiators, heat regis-
ters, stoves or other appliances that produce heat. Also avoid putting the unit in the direct rays
of the sun.
3) For indoor use only.
PLACEMENT
1) Accessibility. It is normal for an audio device to run warm if used for prolonged periods.
Always place your device away from children and pets to prevent burns.
2) Ventilation. Proper ventilation is critical for safe and reliable operation of all vacuum tube
based equipment. This product should not be placed in a built-in installation or rack unless
proper ventilation is provided or the manufacturer’s instructions have been followed. Never
place anything on top of your preamplifier that could obstruct airflow and cause vacuum tubes
to overheat and damage the unit. Do not place your preamplifier in a closed bookcase; over
heating could occur. Ensure that there is at least 8” (200 mm) of open space above the pre
amplifier.
3) Surface. Place the unit on a flat level surface. Care should be taken to prevent objects from
falling and liquids from spilling into the unit. Do not subject the unit to excessive smoke, dust,
vibration or shock.
MAINTENANCE
1) Cleaning. Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners
or aerosol cleaners. Use a dry cloth for cleaning. Do not use any type of abrasive pad, scour-
ing powder or solvent such as alcohol or benzene.
2) Tube replacement. Vacuum tubes have life in the 5000 hour range. We recommend replac-
ing the tubes after 24-36 months, depending on your listening habits. That will ensure that the
preamplifier always performs at its best and tube failure will not overstress other parts of the unit.
3) Biasing the amplifier. Biasing of the Primavera is not required.
SERVICE
1) Replacement Parts. When replacement parts are required, be sure that the service techni-
cian uses replacement parts specified by the manufacturer or parts with the same character-
istics as the original part. Unauthorized substitutions may result in fire, electric shock or other
hazards.
2) Tube replacement. Should it become necessary to replace the vacuum tubes, remove the
AC power plug from the wall and allow thirty minutes (30 min) for the high voltage capacitors
to discharge. Follow instructions outlined below in the section “Handling vacuum tubes”.
3) Modifications. Modifications to the amplifier are strongly discouraged. The unit was de-
signed by experienced engineers and tested for safe and reliable operation. Any modification
may poses safety risk and result in reduced lifetime of the product. Any removal of the cover
will void warranty.
