A.C. RECEPTACLE:

The total power consumption for the 2:50 is 4 Amps @ 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 ﬁrmly seated in the power receptacle before pow-

ering 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.

FUSE:

This is the 2:50’s A.C.’s ( Alternating Current ) main fuse and provides 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 3 Amp SLO-BLO FUSE. A power tube short or failure is often the cause of a blown fuse...Follow the cold start procedure

mentioned earlier in the ON / STANDBY switch section and watch the power tubes as you ﬂip the STANDBY

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 troubleshooting tradition and save the replaced set

as spares. Carry along a few extra fuses for they too could be worth their weight in gold some day.
