AC MAINS FUSE (ABOVE REAR PANEL ON TUBE DECK)

Should your Fuse ever blow from either a surge in the line

voltage or from a faulty power tube, REPLACE IT ONLY WITH A SLO-BLO TYPE FUSE OF THE PROPER RATING AS LISTED

NEAR THE FUSE-HOLDER. THIS IS EXTREMELY IMPORTANT AS THE STRATEGY DRAWS A SUBSTAN-
TIAL AMOUNT OF CURRENT.

FUSE Rating for Domestic (USA) Models - 10A S.B.

FUSE RATING AND REPLACEMENT

A little known fact is that slo-blo fuses, as used in tube amplifiers, are rated for 135%

of stated value for one full hour of operation. This means a 5 amp rated fuse will carry almost 7 amps for one hour before blowing.
In order to comply with UL “fault condition testing” we have furnished a fuse value that will provide trouble free operation while at
the same time being low enough to protect your power transformer from over heating should it ever get too hot (extremely unlikely).

In addition, the high voltage plate of each KT-88 is protected via a special fusing type resistor to remove that tube from the circuit
should it experience a hard short-circuit type failure. This will limit damage and likely allow the amp to continue functioning, getting
you through the gig, though “on one less cylinder”. A hard tube short may occasionally damage the ceramic tube socket and your amp
should be serviced right away by a competent Authorized Mesa technician in the unlikely event this ever occurs.

During two years of prototype development and overall amp torture, the ONLY tube failures occurred when the amp was hit with a
big bass note… and no speaker was connected. To protect against such accidental misuse, we have added internal switches to the
speaker jacks that trigger the MUTE circuit until a plug is inserted into any one of the speaker jacks. For this system to be totally effec-
tive, you must insure that the plug is FULLY inserted into the amplifier and that the other end of the speaker cable is also connected
to your cabinet (duh!). Failures resulting from “no load” misuse will not be covered under warranty as they constitute gross user error.

NOTE: We cannot overemphasize the importance of making sure you have a speaker properly connected to your STRATEGY AT ALL
TIMES. The higher plate voltages of KT-88 power tubes creates potential for expensive repair bills and premature tube failures with
no speaker load connected. Never play loud or long if you hear no sound from your amp and always check the speaker connection
first in any no sound situation.

NOTE: Remember—the Front Panel MUTE LED Indicator will illuminate as a safeguard against a no load condition when there is no
speaker jack connected to the SPEAKER OUTPUT! If you see this light on—CHECK YOUR SPEAKER OUTPUT and PUT A LOAD
(cabinet) ON ONE if necessary BEFORE TURNING STANDBY ON!

POWER CABLE

The IEC Removable AC cord that is supplied with the STRATEGY makes set-ups and tear-downs after the gig

a snap. Make sure the AC cord is firmly in its socket (receptacle) before powering up the amplifier. Also, make sure the AC wall outlet
you are connecting to is a reliable source of 120 (117) volt AC power. Additional heavy-duty cords are available from MESA should
you ever need one... simply call us and we can send one directly to you for a nominal charge (plus shipping).
