Installation

Unpacking

Obviously, the purpose of pack-
ing materials in the transporta-
tion of heavy amplifiers is to pro-
tect the product on its perilous
journey from manufacturer to
proud owner. 
Unfortunately, in our experience
this often results in sprained
backs and bleeding fingers at
the moment of truth: the uncrat-
ing og the beast.
The mephisto comes in a dedi-
cated flightcase offering excel-
lent protection - keep this for
eventual future use. Do not try to
lift it out without help,. do not lift
with you back but bend your
knees and lift with your legs. Do
not at any time let the amplifier
rest on its faceplate, but always
on its feet. 
Enclosed i box is:
1  Mephisto
2  Pair of gloves
1  Acrylic polish
2  AC power cords
1   Warranty card
1 green bias cable

If anything is missing or dam-
aged, please contact your

Gryphon dealer immediately

AC Power

VERY IMPORTANT

Before installation, you must
ensure that sufficient current is
available from you domestic AC
power supply:

Minimum: 10A for 220/240 V
Minimum: 20A for 100/120 V
It is also very important that the
wiring from your AC breaker can
carry the high constant AC volt-
age with only a minimum of loss.
A conductor with a minimum
gauge of 1.5 sq. mm. is recom-
mended.
The Mephisto should ideally be
connected to a separate AC
breaker group independent of
other equipment.

Placement

The Mephisto is a high bias
Class A design and

MUST

be

placed so that air may circulate
freely around the heatsinks. The
Mephisto is equipped with tall
feet for free air circulation, even
on thick carpets. The feet also
allow you to push the amplifier
across the floor without lifting it.
