Do not place the amplifier in such a position where it may get splashed with
liquid or water, e.g. near tables of drinks or near equipment that contains
water, e.g. smoke and bubble machines
Never stand bottles or containers of liquid on the amplifier. If any liquid is
accidentally spilled into the amplifier, unplug it from the mains supply
immediately and take the amplifier to a qualified technician for inspection.
Do not place objects on the amplifier that could fall inside and cause a
malfunction, e.g. coins, tools, etc.
5) Sound level
The level of sound or 'volume' you choose to use will mainly be dependant
on the size of the room you are playing in and you should use the volume
level that gives you the desired results. Always operate the amplifier at the
lowest level you can in any given situation. Each room will have a sweet spot.
Play at too low a level and the instrument will not react with the amplifier, too
high and the instrument will be unplayable. In all cases you should use a
level that you feel comfortable with.
The Human ear is a very sensitive instrument and can easily be permanently
damaged by exposure to the high sound pressure levels that can be
produced by this type of amplifier. Do not operate for prolonged periods of
time at high volume without suitable ear protection, or at a level that causes
you discomfort in any way.
If you experience any hearing loss or ringing in the ears you should consult a
doctor or audiologist.
6) Fuses and ratings
Your amplifier is fitted with several fuses to protect yourself and the
expensive electronics inside from damage in the event of a malfunction
within the amplifier. The size and rating of the fuses bas been calculated to
offer the most protection from damage possible.
Various circumstances can lead to fuse failure. It is recommended that you
familiarise yourself with the type and rating of the individual fuses fitted to
your amplifier and carry spare fuses clearly marked with you as
replacements.
Occasionally a fuse will fail as a result of a power surge in the supply or as a
result of incorrect connection of the loudspeaker. It is permissible to replace
the damaged fuse with one of the same type and rating as stated on the rear
panel of the amplifier, having first unplugged the amplifier from the mains
supply and allowed it to cool down. If the fuse keeps blowing this indicates
that there is a more serious fault within the amplifier such as a damaged
tube. In this event you must take the amplifier to a qualified technician for
repair.
Never fit a fuse larger than the recommended rating.
The fuses fitted to you amplifier are 'Anti Surge' or 'Slow Blow' or 'Time
delay' type fuses, and have the prefix T or H in the part number. So, for
example, a 5 Amp fuse would be T 5A H. The exact rating for each particular
fuse can be found next to the holder in which that fuse fits. If you are not
sure what to buy when purchasing replacements, take the amplifier with you
and show the rear panel to the retailer.

The exclamation mark contained within a triangle is intended to
alert the user to important operating and servicing instructions
contained in the literature accompanying this product.

user to the presence of un-insulated dangerous voltage within
the product enclosure that may be of sufficient magnitude to
constitute a risk of electric shock.
8) Grounding Instructions
This product must be grounded (earthed). If it should malfunction or break
down the grounding provides the path of east resistance for the electric
current, to reduce the risk of electric shock.
This product is equipped with a power cord which contains a grounding
conductor and a grounding plug. The plug must be plugged into a compatible
mains outlet that is properly installed and grounded in accordance with the
local electrical safety codes applicable to your country.
DANGER!! Improper connection of the grounding conductor can result in the
possibility of an electric shock. If you are in any doubt about the ground
connection check with a qualified electrician before using this product. NEVER
modify the mains power cord. Have a suitable mains outlet fitted!
The wires contained within the supplied power cord are colour coded as
follows:
GREEN & YELLOW – GROUND OR EARTH CONDUCTOR
BROWN – LlVE CONDUCTOR
BLUE – NEUTRAL CONDUCTOR
