Unpacking The Ma352 - McIntosh MA352 Owner's Manual

WARNING:
The supplied Vacuum Tube Shield
Covers must be installed over each
of the four Small Vacuum Tubes
before the MA352 Integrated Am-
plifier is connected to AC Power
and activated for use!!
Failure to do so has the potential to
cause physical harm to human be-
ings and animals.
This could also result in damage to
the Vacuum Tubes and the MA352
Internal Circuitry.
It also prevents the potential of a
Fire Hazard, resulting in damage
to the MA352 and the surrounding
environment.
5. The MA352 Integrated Amplifier has four Small
Vacuum Tubes that are inserted into special
Vacuum Tube Sockets on the Stainless Steel Chas-
sis. Refer to figure E.
Each of the Tube Sockets have four pin openings
to accept the Vacuum Tube Shield Covers. Refer
to figure F.
Carefully install the Vacuum Tube Shield Covers
into each of the Vacuum Tube Sockets orienting
the Shield so the "Mc" on top of the Shield is fac-
ing forward. Refer to figures G and H.
