FUSE: This is the A.C.’s (Alternating Current) main fuse and provides protection from outside A .C. fl uctuations 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 2.5 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 switch section and watch the power tubes as you fl ip the

A.C. RECEPTACLE: The total power consumption for the RECT-O 50 is 2.5Amps @ 120 Volts. Thus, a 15 Amp circuit (which is what most house circuitry is wired with) is adequate. Make sure the Euro style A.C. power cord is fi rmly seated in the power receptacle before powering up the unit. Always connect the A.C. cord to a 3 terminal grounded socket. If none are available, connect the A.C. power cord to a ground lift adaptor and then connect to a 2 terminal outlet. This may also be

necessary from time to time for noise problems.

This style of power cord will make tear-downs and cable routing a lot easier and save you time as well. If you should ever need a replacement, just call and we’ll be happy to send you another one for a nominal charge or visit your nearest MESA/Boogie Pro Center.
