accident or extreme climate changes. Nor does it apply to
normal wear and tear of parts such as valves, fuses, light
bulbs, speakers, controls etc.

In the unlikely event of any defect, please contact an
authorised Hayden dealer. All transport charges are to be
pre-paid by the Owner. Unless your purchase is registered
on-line, normal country warranty laws apply.

DESIGN AND BUILD PHILOSOPHY

In Hayden’s UK hand-wired guitar amps, we have set out to
capture what it was that made the now so desirable
vintage amps so great in the first place.

The Hayden amplifiers are hand-built in the UK using
appropriate construction methods to create guitar amps of
distinctive, yet familiar tone, at affordable prices.

Hayden amps are designed to meet the modern guitarist’s
need for an amplifier that is reliable, easy to set up, and
consistently delivers a good core tone from which to work.
The gain ranges are kept with sensible parameters,
allowing the player to integrate a wide range of pedals into
the set-up. On multi-channel amplifiers, the switching and
controls are kept simple, while still retaining flexibility.
Where fitted, effects loops will accommodate the input and
output levels of a wide variety of pedals and external

processors, while larger Hayden amps feature valve-driven
and recovered, footswitchable sends and returns for
maximum signal integrity. And because all footswitchable
functions are accessed by a single footswitch, they always
remain accessible, even in the event of a footswitch failure.

Hayden hand-wired guitar amps feature valve circuitry from
start to finish – indeed semi-conductors are only used in
the power supply and footswitching circuits.

Transformers are comfortably over-specified and thermally
protected for long-term reliability, and chassis are
constructed from non-magnetic and corrosion-resistant
stainless steel.
Where appropriate, printed circuit boards are used, with a
variety of techniques employed to maximise the advantages
of each construction method as follows:

Tag Board

Gold plated tags are inserted into the printed circuit board
and the components soldered to the tags, ensuring all the
benefits of this traditional construction system without the
tiny interconnecting wires which can be prone to breaking.

Tag Board NT

As above but without the tags, components are soldered
into eyelets within the board, allowing replacement without
removing the board.

Full PCB

Used on the larger, more complex amplifiers, only small
signals and currents pass through the tracks, with heaters,
anodes, etc. hard-wired off the board. This approach
provides the consistency and repeatability of PCBs, without
the arcing risks normally associated with this type of
construction. Once again, components that are prone to
damage can be easily accessed without removing the
boards.

IMPORTANT SAFETY
INSTRUCTIONS

HAND WIRED

GUITAR AMPLIFIERS

This Hayden amplifier has been designed to provide
you with many years of faithful service – on the road,
in a studio or in a domestic environment. By following
the rules set out below, you will ensure that the unit
functions safely.

Valve (tube) instrument amplifiers contain very high
voltages and fragile glass tubes and should therefore be
handled with care. A number of important precautions
which must be observed are set out below.

Before using the amplifier, run through the check list below.
If you are in any doubt about any aspect of the amplifier’s
operation, stop using it immediately and do not resume
operation until the amplifier has been thoroughly inspected
by a qualified technician.

1) Storage and moving

When your amplifier is not in use make sure that the
power cord is unplugged from the mains outlet, and that all
leads are removed from the amplifier, including jack leads
and footswitch leads. Jack socket connectors are self­cleaning, so the process of plugging in and unplugging the
leads when not in use will ensure that the internal contacts
will be cleaned when you plug in again.

Store your amplifier in a warm, dry place away from
moisture and condensation. A motor vehicle or cellar may
look dry but condensation can form inside the unit causing
short circuits and possible electric shock. If you suspect the
amplifier may have become exposed to moisture, move it to
a warm dry place and leave it to dry out for at least 48
hours before attempting to use it.

Condensation can also occur when you move the amplifier
from a hot humid place (such as a nightclub) to a cold
place (like a motor vehicle). In such instances, always move
the amplifier into a warm dry room to prevent damage.

When moving the amplifier, handle it as carefully as you
would your instruments. Although solidly built, an amplifier

is easily damaged by shock, so be careful not to drop it or
allow it to fall over. Use a protective cover to protect the
finish and, if you are transporting it with other equipment,
make sure that the amplifier is on a solid floor at the
bottom of the pile.

Amplifiers are heavy. Take care when lifting, always use the
handles fitted to the amplifier to move it, and get help if
you have to lift the amplifier to a greater height than you
feel comfortable with.

Never attempt to operate the amplifier after it has been
dropped. Take it to a qualified technician and have it
checked before using it again.

2) Leads and plugs

Your amplifier contains possibly lethal voltages and must
therefore be connected to the mains using the correct power
cord, which is a three terminal type with a ground connection.

The power cord supplied with the unit should be of the
correct type. If it does not fit your mains outlet consult your
dealer or a qualified electrician for advice before attempting
to use the amplifier.

Never modify the power cord or attempt to use it with a two
pin outlet. Store all your leads in a dry case and take care
when packing them away. All leads, including guitar leads,
are easily damaged with careless handling, so it is a good
idea to carry a spare lead of every type you use. Flexible
power cords get damaged very easily. At the first sign of
damage, discard it and purchase a new one. Always
replace the power cord with one of the same type. Moulded
cords are the best choice with both plugs permanently
fitted to the cord.

When using your amplifier and other equipment it is a good
idea to connect to the supply using a unit known as an
R.C.D. These units are not expensive and offer the user
additional protection against electric shock. An electrical
shop should be able to supply you with a suitable unit.

3) Before Use

Inspect your amplifier for damage before use. Check each
lead for damage before you plug them in to the amplifier,
and ensure that the loudspeaker is connected before you
switch the amplifier on.

Never try to operate the amplifier without the speaker
connected. If you do, serious damage to the amplifier will
result which will be very expensive to repair.
Double check the connections you have made to your
amplifier and make sure you have connected the speaker
to the correct outlet socket that matches the cabinet you
are using. The impedance of the speaker is important and
is usually shown on a plate affixed to the back of the
cabinet, so if the cabinet is 16R (Ohms) then you plug into
the 16R outlet on the amplifier. (See additional notes on
this subject later in the manual).

4) Using the amplifier

When you set the amplifier up for use, it is important that
you adhere to the following rules:

Place the amplifier away from sources of heat, including
radiators, etc. The amplifier itself will get hot in normal use.

Make sure that all the grilles on the amplifier are not
obstructed in any way so that cooling air can circulate
through the amplifier. Do not place anything on or behind
the amplifier that might restrict the flow of air. This includes
items of clothing, or other equipment.

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 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.
