The Sphinx Myth 1 design
This service manual will help you to optimally
service and repair the Sphinx Myth 1 Preamplifier.
This pre-amp uses the newest technologies and
refined designs and is extremely simple to operate.
Designs that successfully have been used in the
award winning Project Eight.
Such as the ultra-linear extremely low-noise
Class-A audio circuits, built from the finest hand-
selected parts.
The signal path is completely balanced from input to
output, and left and right are totally separated.
The power supply is of a unique design (fully Class-
A!) and consists of three completely separate and
independent sections: one for the digital control,
plus one each for the left and right channel.
Input selection is done by means of precision
relays. The ALPS volume control is motor-driven.
To obtain the maximum quality from this power amp
it is necessary to use it with top quality audio
components, preferably with other Sphinx
components.
1. UNPACKING
Before leaving the factory every Myth 1 is subjected
to stringent and extensive technical and exterior
quality inspection.
This ensures you will enjoy many years of high
quality audio from a perfect-looking product.
After unpacking your Myth 1, we therefore
recommend you carefully check it for any transport
damage.
In case of damage: please contact your Sphinx
dealer immediately and retain all packing materials
for possible proof of damage and possible claims.
Even if the component is in perfect condition you
should still keep the packing materials. If you need
to transport your Myth 1 at a later time it will be best
protected by the original packing materials.
