Setting up, wiring, using the unit for the first time
Unpacking
Carefully unpack the amplifier and store the original
packing material carefully. The carton and packing are
specially designed for this unit and will be needed again if
you wish to move the equipment at any time.
If the unit gets very cold (e. g. when being transported),
condensation may form inside it. Please do not switch it
on until it has had plenty of time to warm up to room
temperature, so that any condensation evaporates
completely.
Setting up
Before placing the unit on a sensitive surface please
check the compatibility of the laquer and the unit's feet on
a non visible point.
The unit should be placed on a rigid, level base. When
placing the unit on resonance absorbers or anti-resonant
components make sure that the stability of the unit is not
reduced.
The amplifier should be set up in a well ventilated dry
site, out of direct sunlight and away from radiators.
The unit must not be located close to heat-producing
objects or devices, or anything which is heat-sensitive or
highly flammable.
When installing the amplifier on a shelf or in a cupboard it
is essential to provide an adequate flow of cooling air, to
ensure that the heat produced by the unit is dissipated
effectively. Any heat build-up will shorten the life of the
amplifier and could be a source of danger.
Coution!
There must be plenty of space around the amplifier
on all sides so that waste heat can dissipate freely.
Maintain a minimum distance of 20 cm to walls,
ceilings, shelves or other objects which could
hinder the circulation of cooling air.
Do not place any object on top or below the
amplifier.
Ensure that the fan on the underside of the
amplifier is not blocked or obstructed, and that air
can enter the fan unhindered.
Set up the amplifier in such a position that children
cannot touch it.

For electrical safety: Device may not be operated
without tube cover!
Mechanical de-coupling
The quality and characteristics of the base on which your
high-quality Hi-Fi equipment stands define the limits of
sound quality which can be achieved. The base surface
should be as heavy, rigid, hard and level as possible.
This amplifier is supplied with the new  damping
cones. This feet feature internal damping qualities which
effectively de-couple the unit from the base surface.
These features ensure that vibration in the base surface
is absorbed, and the delicate valves are protected from
interference caused by microphony effects.
The amplifier should be set up in an open position to
ensure that the vibration absorbers are able to work
perfectly. Do not allow any part of the case to touch walls
or other surfaces.
Note:
If the base surface is uneven you can screw the
standard feet in or out to set the unit exactly level.
All units must be adjusted so that they are exactly
horizontal in all directions. Check that all feet make
solid contact with the base surface, i. e. that there is
absolutely no tendency for the unit to wobble.
