1. POWER SWITCH
On/Off Switch for mains power to the amplifier.
Please ensure the amplifier is switched off and
unplugged from the mains electricity supply before
being moved.
2. STANDBY SWITCH
The Standby Switch is used in conjunction with the
Power Switch to 'warm up' the amplifier before use
and to prolong the life of the output valves. When
powering up the amplifier always engage the Power
Switch first. This allows the application of the voltage
required to heat the valves to their correct operating
temperature. After about 2 minutes, when the valves
are up to the correct temperature, the Standby
Switch can be engaged. Upon doing this the H.T.
(High Tension) which is the high voltage required by
the output valves to pass signal (and hence produce
sound) is applied. To prolong valve life, the Standby
Switch alone should be used to turn the amplifier on
and off during breaks in a performance. Also, upon
full power down, always disengage the Standby
Switch prior to the main Power Switch.
3. INDICATOR
The Indicator will be lit when your amplifier is on and
will not be lit when the amplifier is switched off.
4. SPEED CONTROL
Controls the speed of oscillation when using the
Tremolo effect.
5. INTENSITY CONTROL
Controls the intensity of oscillation (i.e. the effect
depth) when using the Tremolo effect.
Note: The tremolo effect will only work when playing
through Channel 2 of the 1962 combo.
6. PRESENCE CONTROL
Adds higher frequencies to the guitar tone, creating
crispness and bite. Turning this up will make the
sound more cutting and 'present'.
7. BASS CONTROL
Controls the amount of low frequencies or bottom
end in your tone.
8. MIDDLE CONTROL
Dictates the middle register of the amplifier. Turning
this up will make your guitar sound fatter. Conversely

reducing the amount of middle in your tone will result
in a sharper and thinner guitar sound for a more
'scooped' tone.
9. TREBLE CONTROL
Controls the high frequencies of the guitar tone,
making your guitar sound brighter when increased.
Note: The tone network is highly interactive and
altering one control can change the shape of
the sound in relation to the other tone controls.
Experimentation is the best way to achieve your
desired sounds.
10. VOLUME I
Controls the overall output level of Channel 1.
Note: This channel is voiced for a higher treble
response than Channel 2.
11. VOLUME II
Controls the overall output level of Channel 2.
Note: Channel 2 is voiced for normal response.
12. INPUT JACK
Connects the guitar to Channel 1.
Note: Though the first input of the first channel is
the input that most guitarists use, don't be afraid
to experiment. Some guitar players prefer to mix
the two channels together by connecting a short,
screened patch lead between the second input of
Channel 1 and the first input of Channel 2. If you
then plug your guitar into the
first input of Channel 1 (item 12),

Connects the guitar to the lower sensitivity input on
Channel 1.

1. FOOTPEDAL JACK
For connection of the supplied footswitch to allow
Tremolo to be switched on and off.
2. LOUDSPEAKER OUTPUT
This is for connection to either the internal speakers
and/or an external load, i.e. speaker extension
cabinet.
3. OUTPUT SELECTOR
Matches the amplifier's output to the load
impedance. With all-valve amplifiers it is imperative
that the amplifier is connected to a load whilst in
operation and that the impedance selected on the
amplifier matches the total impedance of the internal
speakers and/or extension speaker cabinets.
Important Note: Failure to do so will result in
damage to the amplifier. The two internal speakers
are 16 Ohms each. These are wired in parallel
giving an overall impedance of 8 Ohms, therefore
the output selector should be set to 8 Ohms. If a 16
Ohm extension speaker cabinet is used instead of
the internal speakers the output selector should be
set to 16 Ohms.
Note: No additional extension speaker cabinet
with an impedance lower than 8 Ohms should be
used. Failure to comply with these points will result
in damage to the amplifier. Your amp should be
completely powered down before the selector is
turned.

Note: The electrical characteristics of the 1962HW's
transformers are identical in every single aspect to
2
the original ones used back in 1965. The inclusion
of the 100V Line tap, while being historically correct,
is of little or no use on this particular model, if truth
be told. The reason it was present in the 60s was
because certain amps were able to drive multiple
remote 100V line speakers in various locations

but vestigial feature!
4. MAINS SELECTOR
Matches the amplifier mains transformer voltage to
the incoming mains voltage. Ensure that the rotary
Mains Selector is set to the correct mains voltage
applicable to the country where used. If you do
not know the mains input voltage contact your
authorised Marshall dealer.
Your amp should be completely powered down
before the selector is turned. Adjustment from 230v
to 120v to 100v or vice versa will require the mains
fuse to be changed to the corresponding value as
detailed on the rear panel.
5. H.T. FUSE
The correct value of H.T. fuse is specified on the rear
panel of the amplifier.
6. MAINS INPUT
Your amp 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 shown 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 get advice from a
qualified person. Your Marshall dealer will help in
this respect.
7. MAINS FUSE
The correct value of mains fuse is specified on the
rear panel of the amplifier.
