IMPORTANT READ THIS FIRST
Box contents:
Amplifier, Cover, 4x 6L6/KT66, 4x 6SN7, remote
control (option), mains lead, manual, screwdriver.
1 Unpack unit carefully and check that it is in
good condition. Report any transit damage to your
re-seller immediately. It is important that you keep
packaging for warranty/service return.
2 If Necessary fit the valves, or check that they
are firmly in place. The 6L6/KT66/6P3s should
be fitted first observing the numbers 1,2,3,4 on the
rear of the valve, corresponding with the four
sockets viewed left to right from the front. Take
care to line up the centre spigot when inserting all
valves. Do not push or pull the output valves
by the glass envelope, this could cause the
glass envelope to become detached from the
base, damaging the valve.
The four smaller 6SN7/CV181/6N8 valves are
fitted at the front. Again observe the position of
THE "spigot". These are numbered 5/6/7/8. Fitting
the valves as numbered does not require any
adjustment.
Please
note
the
interchangeable with the 6L6/KT66 this could be
dangerous and will damage the amplifier.
3 Connect to source units, e.g. CD, Tuner,
Tape, Phono pre amp (if used) etc via appropriate
phono sockets.
4 Connect loudspeakers to the BLACK terminal
and either 4 or 8 Ohm RED terminals. (See your
speaker info). Make sure the polarity is correct.
(See speaker connections chapter). If 'bi-wiring'
both black and both red leads should be
connected together. A second banana plug can
go vertically through the terminal hole.
5 Connect to mains supply using supplied IEC
mains lead to 230/240v supply (or 117v North
America). If for some reason the welded (fixed)
plug must be removed, remove the fuse and
dispose of immediately. (As they can be a
danger to children if plugged in). The replacement
plug should be wired in the following way Brown
to Live terminal, Blue to Neutral terminal and
Green/Yellow to Earth.
6 SWITCH ON! The meter should light up, the
valves will heat up. The amplifier will start working
within about 45 seconds. All valves should have a
visible orange glow from the cathode heaters.
With the volume control set to minimum (fully anti-
clockwise) there should be virtually no sound
coming from the speakers except a barely
discernible hum. If there are any unpleasant
sounds coming from the speakers, switch off and
refer to the 'Trouble Shooting' section or contact
your dealer or Icon Audio. When using for the first
time check the bias reading The pointer should be
in the black section (see section 6.2). Select
source required and adjust volume control.

7 Your unit should now be functioning. If not
check wiring again making sure the correct input
is selected and volume control is not at "zero". Do
not operate at a high volume for the first five
minutes to allow the valves to warm up properly.
8, Remote Control. (Optional version) If there is a
plastic safety tab, loosen rear screws and pull out,
re-tighten screws. If the batteries are OK (2x AAA)
the blue LED should light when any of the keys
are pressed. A little skill is needed in pointing and
pressing, as the unit has a motorised "pot" which
may not be as responsive as your TV. Maximum
range is about 5 meters. System re-sets to 9
o'clock on switch on. Strong light may interfere
with operation. Batteries should be replaced every
two years to prevent leakage.
when amplifier is not in regular use to prevent
leakage.
Please note all these things are normal for
valve amplifiers:
A, Valves can get very hot, BEWARE!
B, The middle transformer will get "hand hot".
C, The amplifier may smell slightly for a few weeks.
D, Occasional Mobile phone 'breakthrough' is
normal (move your phone away!).
E, Valves may make a 'tinkling' sound when
warming up and cooling down.
F, The volume control may sometimes appear to
sound 'Scratchy', this is not a fault!
G, Valves occasionally "Pop" or "Crackle". If this is
regular

8 Health and Safety. The valves when operating
have high surface temperatures. Keep out of
reach of children and pets. The use of the
supplied

circumstances. Avoid situations where flammable
material such as paper or curtains may come into
contact with the valves. Always unplug when
making adjustments. Like all amplifiers there
are potentially lethal high voltages inside,
which when switched off can take a few
minutes to discharge! Do not remove bottom
panel unless you are a competent engineer.
There are no user serviceable parts inside. Like
other household electrical appliances do not
leave unattended whilst switched on. Do not
adjust the output valve grid bias pre-sets without
reference to the manual. Incorrect adjustment
could cause the valves to overheat, with resulting
in damage to valves and amplifier.
To maintain the best performance of the
amplifier you should check the bias of the
output valves regularly (say monthly using
built in meter). Full details will be found in
section 7.
