Mesa/Boogie Vacuum Tube Audio 用户手册

PAGE 01

Your 

Mesa Engineering amplifier is a professional instrument. Please treat it with respect  and operate it properly.

•  Do not expose amplifier to moisture, rain or water, direct sunlight or extremely high temperatures.

•  Always insure that amplifier is properly grounded.

•  Always unplug A.C. power cord before changing fuse or any tubes. 

•  When replacing fuse, only use same type and rating.

•  Avoid direct contact with heated tubes. 

•  When handling tubes, use gloves or a paper towel to prevent getting oils from your skin in contact with the tube’s glass 

envelope. This could cause premature tube failure.

•  Insure adequate air circulation around your amplifier.

•  Use tube cage in the presence of small children and animals.

•  Be sure to connect to an A.C. power supply that meets the power supply specifications listed on the rear of the unit. This is 

especially important if you use your amplifier in a country other than the  USA. Check that the voltage indicated on the rear 

chassis matches that of your country’s line voltage.

•  If there is any danger of lightning occuring nearby, remove the power plug from the wall socket in advance.

•  To avoid damage to your speakers and other playback equipment, turn off power to all related components before making 

any connections.

•  Do not use excessive force in handling control buttons and switches.

•  Remove the power plug from the A.C. mains socket if the unit is to be stored for an extended period of  time.

•  Do not use solvents such as benzene or paint thinner to clean the unit. Wipe off the exterior with  soft cloth.

•  Do not remove rubber feet. This would restrict air flow underneath the amplifier and could result in  damage due to 

overheating. 

•  Do not install in enclosed space unless proper ventilation is provided.

•  In the unlikely event of massive tube failure (arcing and lightning inside the glass envelop),  immediately turn off power and 

disconnect power cord.

 •  Do not remove any chassis parts to get inside your amplifier. There are no user-serviceable parts  inside. Tube amplifiers 

operate with very high voltage. Unskilled repair attempts could result in serious injury. Leave repairs to qualified technicians.
