• When moving your amplifier from a cold environment
to a warm environment, condensation can occur inside
the amplifier. Always allow your amplifier to acclimate
to room temperature before operation.
• Do not operate your amplifier in extreme hot or cold, or
in wet conditions.
• Keep your amplifier free of dirt, dust and moisture. If the
covering of your amplifier requires cleaning, use a light
soapy solution on a damp cloth. Avoid getting liquid
inside the amplifier or on the control panel surfaces
• Avoid rough handling, dropping or extreme vibration to
your amplifier.
• Always take care when transporting your amplifier.
• Do not block the vent openings of your amplifier. This
can cause the amplifier to overheat.
•
If you notice a change in the performance of your
amplifier, take it to a qualified service professional to
diagnose the operating condition of the amplifier and
the tubes.
• Tube life varies based on the frequency, duration and
level of use. Tubes require replacement from time to
time to maintain top performance of your amplifier. If
you are not sure about the operating condition of your
tubes, take the amplifier to a qualified professional for
evaluation of the condition of the tubes
• Do not try to service or modify your amplifier yourself.
This will void the warranty and presents danger of
electrocution. There are no user serviceable parts inside.
•
Always unplug your amplifier from the wall power
source when not in use.
•
Always have your tubes replaced by a qualified
professional.
• Never operate your amplifier without a speaker cabinet
connected via an appropriate speaker cable (not
instrument cable!) to the speaker cabinet.
• Never operate your amplifier at an Ohm load below
4 Ohms.
• Always place your amplifier in “Standby” mode before
turning it on, off, changing the setting of the Half Power
transformer switch or the Triode/Pentode switch.
• When in doubt, have your amplifier evaluated by a
qualified professional!
Tube amplifiers are more sensitive than solid state
