Class5H
OWNER’S MANUAL

JJiimm MMaarrsshhaallll
I would personally like to congratulate you on your
purchase of the Marshall Class5 amplifier.
One of my golden rules has been, and always will be,
to listen to what guitarists want from their amplifiers.
When the company started receiving numerous
requests to produce an amplifier containing all the
harmonics, feel and tone of a classic Marshall stack, but
at a fraction of the size and volume, I set my
experienced R&D team the challenge.
In response, they have created the Class5, a single
channel, 5 Watt, all-valve head brimming with classic
Marshall tone. I was amazed when I heard what this
small amp could do, it really does punch way above its
weight and contains everything from bright cleans to
classic crunch tones.
The high quality construction is something I’m
particularly proud of too. Every Class5 amplifier is
created from specially sourced components and
materials by our highly skilled and dedicated shopfloor
staff at our factory in the heart of the UK. Their attention
to detail and unwavering standards mean your new
amplifier will truly stand the test of time.
I would like to take this opportunity to wish you every
success with your new Marshall Class5 amplifier.
Yours Sincerely,
Dr Jim Marshall OBE

The Class5H is a 5 Watt, all-valve, Class A
amplifier in a head format.
This little amplifier has been manufactured in
response to a very common request we have
received over the years, a request which
nearly always contains the phrase “Can we
have the Marshall Stack sound, but at a much
lower volume”. So here it is, a ‘baby Plexi’ if
you like!
Incorporating a very simple layout of Volume,
Treble, Middle and Bass, it is designed to
deliver those great cranked tones with
minimum fuss and environmental abuse. The
Class5H is a must for recording and is ideal for
rehearsals and smaller gigs. A headphone
output is also included for private practice.
Two ECC83 (12AX7) double triode pre-amp
valves and a single EL84 pentode power amp
valve ensure that the signal path is pure Class
A valve tone from beginning to end.
‘Class A’ topologies are known for their
generous second harmonic distortion
characteristic, which is very pleasant to the ear
and results in some classic overdrive tonality.
Cranking the amp up to it’s full ‘deceivingly
respectable’ output will yield some red hot
Marshall roar which can be driven into either
8Ω or 16Ω extension cabinets.

Before powering-up your Marshall Class5
amplifier, you must ensure that an appropriate
speaker cabinet is connected to the
corresponding impedance matched
loudspeaker jack on the rear panel, (unless
‘headphone’ mode is selected). Failure to do
so could result in serious damage being
caused to your amplifier. Always use an
unshielded loudspeaker cable to connect an
amplifier to a loudspeaker cabinet, never use a
screened (shielded) guitar cable. After use,
always allow the amp to cool down before
moving.
IIMMPPOORRTTAANNTT NNOOTTEE::
Please refer to the ‘Warning’ plate on
underside of the product.
11.. PPoowweerr SSwwiittcchh
This is the On/Off switch for the mains electric
power to the amplifier.
NNOOTTEE::
Please ensure the amplifier is switched
off and unplugged from the mains electricity
supply whenever it is moved!
22.. MMaaiinnss IInnddiiccaattoorr
This red indicator will light up whenever the
amp is plugged into the mains and the Power
Switch (1) is on.
NNOOTTEE::
Please allow a minute or so for the
amp to ‘warm-up’ after switching on. This is
normal with valve amplifiers as valves need to
reach their ‘working temperature’ to operate
properly.
33.. BBaassss
This controls the amount of low frequencies
(bottom-end) in your tone.
44.. MMiiddddllee
This controls the mid-range of your sound.
Turning this up will make your guitar sound
fatter and fuller.
55.. TTrreebbllee
This control determines the amount of high
frequency (top-end) that is present and gives
your guitar tone a defining edge as it is turned
up.
66.. VVoolluummee
This control sets the overall output volume of
the amplifier.
TTOONNAALL TTIIPP::
It is practical to set this first to suit
the environment in which you are playing, as
the position of this volume largely dictates the
optimum positions for the other controls.
77.. IInnppuutt JJaacckk SSoocckkeett
This is where you plug your guitar into the
amp. You must use a screened (shielded)
guitar cable. Never use an unscreened
(unshielded) speaker cable. The input to any
guitar amplifier is a very sensitive part of the
signal path and is very sensitive to electrical
interference, hence the need for a screened
guitar cable. Your screened cable should be of
good quality. If you are in any doubt regarding
this, your Marshall dealer will be more than
happy to help and advise you.

WWAARRNNIINNGG::
Although your Class5 amplifier
has 2 extension speaker outputs (and a
headphone socket), never attempt to connect
cabinets to both extension speaker outputs
simultaneously. Only use one speaker output
at a time, the recommendations are: 1x8 Ohm
or 1x16 Ohm or headphones. Combining
these options may stress the power amplifier
section and, in extreme cases, may lead to
valve and/or output transformer failure.
11.. EExxtteennssiioonn SSppeeaakkeerr 88
Ω
This is the output that connects to an 8Ω
extension cabinet.
22.. EExxtteennssiioonn SSppeeaakkeerr 1166
Ω
This is the output that connects to a 16Ω
extension cabinet.
33.. HHeeaaddpphhoonneess//EExxtteennssiioonn SSppeeaakkeerr
SSeelleeccttoorr SSwwiittcchh
This switch routes the 16Ω output signal to its
dedicated speaker output (2) or the
headphone output (4). When this switch is set
to ‘Headphones’ this is the only time it is
acceptable not to have an extension speaker
cabinet connected.
44.. HHeeaaddpphhoonneess OOuuttppuutt
This is the output that connects to a standard
set of headphones.
TTEECCHH NNOOTTEE::
The signal here is derived from
the speaker output with added filtering in
order to include the power amp and output
transformer’s contribution to the overall tone.
An internal 16Ω dummy load helps maintain
the correct ‘reflected’ impedance for the power
amplifier.
55.. MMaaiinnss IInnppuutt
Your amplifier is provided with a detachable
mains (power) lead, which is connected here.
The specific mains input voltage rating that
your amplifier has been built for is indicated
on the back panel. Before connecting for the
first time, please ensure that your amplifier is
compatible with your electricity supply. If you
have any doubt, please ask the advice of a
qualified technician. Your Marshall dealer will
help you in this respect.
The correct value of mains fuse located in the
small drawer at the bottom of the mains socket
is specified on the rear panel of the amplifier.
The drawer contains a space for a spare fuse.
NEVER attempt to bypass the fuse or fit one of
the incorrect value!
NNOOTTEE
: It is wise to carry spare fuses at all
times.
