Anthem Audio Amp 1 - Manual (Page 7)

INSERTION OF THE TUBES
1. Using the screwdriver supplied, remove the cover of the
Amp 1. For your convenience, only two of the screws are
installed at the factory.
2. When handling the tubes, it is recommended that the
cotton gloves provided be worn to prevent skin oils from
depositing on the glass surface and possibly causing the
tube to become prematurely “gassy”, thereby shortening
the tube’s useful operating life.
3. Noting the location of the tube sockets in the top view
photo, inspect the tubes for corresponding labels and
markings. Once locations are mapped, take a tube and
inspect the pins, noting the larger space between two of
the pins (see Figure 2). This space will match with the
socket. Insert each tube into the appropriate tube socket,
making sure all pins and pin holes are aligned. Do not
force the tubes into the sockets. “Rock” the tubes gently
while pushing slowly until each tube is firmly seated.

Before plugging in the Amp 1, check to see that the unit is
configured for the correct AC line voltage for country of
use. The operating AC line voltage is indicated on the side
of the shipping box. If the Amp 1 is set incorrectly for the
country in which it is to be operated, contact the dealer or
distributor in your area. If the unit is configured properly,
continue with operation.
Connect the Detachable Power Cord to the Amp 1 AC
Power Cord Socket (H) (see Figure 4). Plug your Amp 1
into the AC power source.
Connect loudspeakers to the appropriate post as
described in the connection section of this manual.
The two remaining connections are made with co-axial
cable and RCA connectors to a suitable Preamplifier such
as the Anthem Pre 1.
Connect the pre amp to the Amp 1 Inputs (E); left channel
to left channel and right channel to right channel.
The Amp 1 is now ready for operation. Power the Amp 1
by placing the On-Off button (G) in the ON position. The
tubes will take approximately 30 seconds to warm up and
then the Amp 1 is functional.
Note the larger space
between two of the pins and
holes for proper alignment
of tube and socket.
