 T

o reduce the risk of electrical shock, do not 

remove the back cover of the amplifier. Inside parts can be 

repaired only by qualified service personnel.

 

WARNING:

expose this appliance to moisture, rain or any liquid.

This symbol is intended to 
alert the user to the presence 

of dangerous voltage and

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.

Do not use the amplifier in humid and dusty places.

Do not operate the amplifier through the unearthed socket.

Leave the amplifier and bias settings to qualified personnel.

Tubes could get heated intensively, do not touch it or it could cause burning.

Do not leave the apparatus in the vicinity of children.

Unplug the amplifier before tube change, unplug the cord and wait for the tubes to cool 
down.

Before changing the fuse, switch the amplifier off and unplug the cord. Also, make sure you 
use the fuse of the proper power.

!! Keep this instruction for the future use !!
