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 30 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   two   Celestion   G12H   speakers   from   the   Heritage   series,   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.
