QUICK SET UP GUIDE
1 Unpack unit carefully
. Make sure that it is in good
condition. It is important that you keep packaging for
warranty/service return.
2 Fit the valves if necessary.
This should be easy as there are only one type of
valve.
Do not push or pull the 6SN7s glass
envelope
, this could cause the glass envelope to
become detached from the base causing irreparable
damage.
3 Connect between either your source unit or
between your pre and power amplifier.
e.g. CD,
Tuner, Tape, Phono pre amp (if used) and power amp
etc via appropriate phono sockets and leads.
4 Connect to mains
supply using the attached mains
lead to 240v supply.
If it is necessary to change to
a different type of mains plug, the welded plug
must be removed and replaced with a suitable
type. Please then remove fuse and dispose of
carefully.
(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 terminal.
6 SWITCH ON!
The blue mains indicator should light
up and unit will take approximately 40 seconds to
start working. 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 no sound coming from the speakers except
a barely discernable gentle hum.
7 Your unit should now be functioning
. If not check
wiring again and/Use selector/tape monitor/volume to
choose source program and suitable listening volume.
The best sound quality will be when the unit has
warmed up for at least 20 mins.
8 Health and Safety
. The valves when operating
have moderately high surface temperatures. Keep out
of reach of children and pets.
Under no circumstances operate with valves
removed!
Like all amplifiers there are potentially lethal
voltages inside (300v DC), which when switched
off can take up to 15 mins 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.
Connecting inputs & outputs
Many problems with hi fi equipment involve
connecting leads which are usually either
‘Bad, or
Wrong connection’
. So it’s worth making sure that
you have good connections and that your leads are
the right way round.
Inputs
The amplifier will work with any standard piece of hi fi
e.g. CD, Tuner, Tape Deck, Mini Disc, TV, Video
Recorder, DVD etc.
General points
•
Mobile phone ‘breakthrough’ is normal
•
A switch-off ‘click’ through the speakers is
normal.
•
Storage in damp conditions could damage
transformers.
Connecting Leads
Use good quality connecting leads, which are no
longer than they need to be.
Leaving the amp switched on
People sometimes ask if the amp should be left
running 24/7 without switching off. Whilst the amplifier
will sound at its best when it is properly warmed up,
there is no advantage leaving it switched on when it is
not in use. It is using electricity and valves have a
finite life. Conversely the valves and other
components are stressed more at switch on; therefore
do not switch on and off unnecessarily.
Although the
amplifier should sound good within about 20
mins, like most hi fi units it can take up to an hour
to sound at its best and will take a couple of
months of regular use before it is ‘run in’.
Cabinet Care
To remove dust from the cabinet and valves we
suggest gentle brushing with a soft paintbrush and a
duster. Finger marks can usually be removed with a
damp cloth. Always clean with the power
disconnected.
CAUTION – HEALTH & SAFETY!
When making any adjustments remember to
isolate from power supply, and remember that
high voltages can remain present inside for some
time after switch off.
