Specifications
This is the A.C.’s (Alternating Current) main fuse and provides electrical current protection from outside A.C. fluctuations, as well as
power tube failure damage. Should the FUSE blow, replace it with the same rating in a slo-blo type package. The domestic U.S.
version requires a 2 amp slo-blo fuse. A power tube short or failure is often the cause of a blown fuse...Follow the cold
start procedure mentioned in the ON/STANDBY toggle switch section and watch the four EL84 tubes as you flip the
STANDBY switch to the ON position. If a power tube is going bad or is arcing you will see it! Flip the STANDBY switch
to Standby immediately and replace the faulty power tube and the fuse if necessary. If you see nothing abnormal as you
lift the STANDBY switch, it is possible that a power tube shorted temporarily and blew the FUSE. If this is the case it may
work again normally. To be extra safe you may want to replace all power tubes in the “shotgun troubleshooting tradition
and save the replaced sets as spares.
NOTE: Like tires on a car, spare tubes and fuses are always a measure of good insurance. Your MAVERICK was carefully
constructed with reliability in mind! Given the proper care and maintenance, it will deliver years of trouble free service. However, any
pro guitarist who is out there gigging will tell you; spare tubes and fuses are a must for the fabled cord bag and may be worth their
weight in gold some day.
This switch reverses the polarity of the A.C. ground. It can be helpful in eliminating annoying hum or A.C. buzz as well as those painful
microphonic shocks. It should be left in the center OFF position when neither of these problems are occurring.
This 1/4” jack allows you to control the Reverb remotely when a cable and Mesa Dual Footswitch are connected. This footswitch is an
option and can be ordered by calling us direct, or by contacting your nearest Mesa/Boogie Pro Center.
