Maintenance

Important Safety Information

 

SERIOUS INJURY OR DEATH CAN OCCUR AS A DIRECT OR INDIRECT 
RESULT OF ELECTROCUTION.

 

There are lethal voltages present inside the chassis on multiple exposed terminals. 

Under certain circumstances this Amplifier is capable of storing lethal charges for 
extended periods of time, even if it has been disconnected from the wall outlet. 
Always fully discharge power supply capacitors before commencing any work inside 
the chassis.

Under no circumstances attempt to make any bias adjustments while holding a 
guitar that is plugged in to the Amplifier. 

This amplifier must ALWAYS be grounded (earthed) by use of a 3 Pin Power Cord.
3 Pin to 2 Pin converters are unsafe and leave the amplifier without a suitable 
ground fault path, this can lead to damage, injury or death if an internal fault 
should occur.

Never work inside a live chassis. Always ensure the power cable is disconnected 
from the power source.

Service work MUST ALWAYS be carried out by a Qualified Technician There are 
no user serviceable parts inside the chassis. 

We will not support, nor will provide information to any person wishing to 'modify' 
or 'convert'  the equipment in any way from its supplied specification.

Note: Circuit boards may contain areas covered with an insulating non-epoxy 
compound to help reduce induced noise from sources such as fluorescent lights, 
stage lights etc. This potting compound can be easily  removed in the event of 
Amplifier service by using an electrical heat gun on a low setting to make the 
compound pliable.
