5. The C8 Preamplifier has four Small Vacuum
Tubes that are inserted into special Vacuum Tube
Sockets on the Stainless Steel Chassis. 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
facing forward. Refer to Figures G and H.
Figure E
WARNING:
The supplied Vacuum Tube Shield
Covers must be installed over
each of the four Small Vacuum
Tubes before the C8 Preamplifier
is connected to AC Power and
activated for use!!
Failure to do so has the potential
to cause physical harm to human
beings and animals.
This could also result in damage
to the Vacuum Tubes and the C8
Internal Circuitry.
It also prevents the potential of a
Fire Hazard, resulting in damage
to the C8 and the surrounding
environment.
