AMPLIFIER SPECIFICATION

The Alligator series amplifiers are handmade and of full-tube design. From the very beginning

it has been made and tested by musicians who are best aware of the guitarist’s needs. These

amplifiers are for guitarists that play “classical” types of music from jazz, blues, hard rock, to even

heavy metal.

The power stage is based on four EL84 tubes which give it an output power of 50 W. Not only

are these tubes reliable mechanically but also are characterized by creating a warm, “singing” tube

tone. The Preamp is on two 12AX7 tubes. One of the things that distinguish the EL84 tube is that

you only need half of 12AX7 for the inverter, while with EL34 or 6L6 you need to use all of it.

Despite of the preamp having only two tubes, the amplifier is capable of creating a wide spectrum of

tones. The master section of the amplifier has been designed so that when playing at low volume,

the tone quality is maintained. This section is also equipped with a spring reverb.

The amplifier has two channels: clean and distorted. On the clean channel exists the

possibility of obtaining a “crunch” sound and the distorted channel offers possibilities from crunch to

even a high gain sound. Additionally, the distorted channel offers the possibility of having two

independent gains (potentiometer Gain 1 and Gain 2) controlled by a footswitch. For example, the

player may set Gain 1 for less distortion than Gain 2, which with the help of a footswitch, allows for

an easy transition between the two during a solo. This channel offers a wide variety of tones from

classic rock and roll to hard rock, hardcore, even metal.

Combo versions: AD5201 Single and AD5201 Twin have one and AD5202 Single and AD5202

Twin have 2 Celestion Vintage 30 speakers which are connected to the amplifier with a thick speaker

cable with a jack plug. The player may disconnect the internal speaker and connect an external

cabinet even of a different impedance because the amplifier has outlets of 4 Ohms, 8 Ohms, and 16

Ohms impedance.

alert the user to the presence
of dangerous voltage and
constitutes a risk of electrical
shock.

This symbol alerts the user to the

presence of important operating
and maintenance instructions.

Be cautious while transporting the cabinet.

ATTENTION !!!

• Amplifier produces high volume levels. Staying in places of high volume levels could cause

permanent hearing loss.

• To avoid electrical shock never open the amplifier’s cover. In case of failure, refer servicing

to qualified personnel.

• Always use the highest quality signal cables (we recommend Laboga cable “Way of sound”)

and volume signal cables. Using improper speaker cables could cause damage to the
amplifier.
