Always use a grounded AC cord, and make sure that a proper ground connection is
supplied to the amp. Never attempt to lift or defeat the ground connection to the amp.

This fuse is inline with the AC power input, and protects the primary side of the power
transformer. Make sure to use a fuse of the same rating and type specified on the back
panel of the amplifier.

This fuse protects the amplifier if one of the output tubes develops a short circuit. You
should use a standard fast-acting 500mA fuse here.

When powering up the amp, you should start with the Power switch OFF, and the
Standby switch in the "STANDBY" position.
First, turn on the Power switch. This will apply power only to the tube filaments only.
After turning on the Power switch, allow the tubes to warm up for about 1 minute, then
toggle the Standby switch to the “OPERATE” position.
The power-down sequence is not as important as the power-up sequence. When
turning the amp off, you may turn Power off before Standby, or turn Standby off before
Power, or turn them both off at the same time.

When only one speaker is being used (e.g. the internal speaker, if yours is the combo
version of the Majesty), it must be plugged into the “Main” speaker jack. The
Impedance switch should be set to match the impedance of that speaker.
The Extension speaker jack may only be used if there is also a speaker plugged into the
Main speaker jack. Inside the amp, the Extension speaker jack is wired in parallel with
the Main speaker jack. Because of this, we have to consider the impedance of both
speakers connected in parallel, and set the impedance switch to that total combined
value.
