2000 25
TH
ANNIVERSARY uses a standard three prong male
IEC connection for AC input. You need to use a power cord
with a female three prong IEC connector at one end.
INITIAL POWER-ON
Once you have your T-2000 25
TH
ANNIVERSARY in place and
all connections have been made to your turntable and
preamplifier, you are ready to turn on the power for your T-
2000 25
TH
ANNIVERSARY; before you power it up, though, be
sure you have:
•
removed ALL the cushion materials (cardboard around
and “O” rings on tubes) from inside the tube chimneys
•
checked that power tubes are snug in their sockets
and
that the pin alignments for the KT150’s are correct (wide
diameter pins and narrow diameter pins in the correct
holes of the sockets.
This is essential.
The KT150 tubes
are fused, as is the mains for the unit, and they should
preserve both the tubes and the amplifier, in case you
have removed and replaced the KT150’s incorrectly.
However, you will have to replace fuses, and the damage
to your self-esteem for getting it wrong may haunt you
forever. Audiomentors and Allnic Audio Labs are not
responsible for such an outcome.
•
ensured the interconnects are firmly attached
•
turned the preamplifier’s and T-2000
25
TH
ANNIVERSARY
’s volume controls down to zero (if you use
that combination)
and otherwise zeroed or muted the
volume on your source(s).
•
securely and correctly fastened the speaker cables and
ensured that they are also connected properly to the
speakers.
Turn on the T-2000 25
TH
ANNIVERSARY by pushing in the
power switch button located at the right of the front panel
(facing the front of the unit) to the “on” position. The “on”
position is with the button switch depressed. Of course, the
off position is the reverse. After about a thirty to forty (30 -
40) second delay (the soft start), the A-2000 25
TH
ANNIVERSARY will be powered on.
OPERATION - CHASSIS AND REMOTE CONTROLS
When the power is on, the current meters on the face of the
chassis will illuminate. From this point on, the T-2000 25
TH
ANNIVERSARY’s operation is straight-forward. The face of the
chassis has an input selector control knob and a volume
control knob will also control the input selections and the
volume. It will not control the power to the T-2000 25
TH
ANNIVERSARY, which must be switched on and off manually, as
described above. Remove screws on the bottom of the remote
control to replace batteries.
When you are finished listening, turn off your T-2000 25
TH
ANNIVERSARY stereo amplifier(s) first; then, turn off your
preamplifier and sources.
If the T-2000
25
TH
ANNIVERSARY
is
in triode mode at turn-off, it will produce a sound through
the speakers as the amplifier’s relays turn off. Though this
sound is harmless to speakers, some users may prefer not to
hear it. To avoid the sound, simply switch the T-2000
25
TH
ANNIVERSARY
to pentode mode prior to turning it off (see
the “On-the-Fly Triode/Pentode Switching section below).
In the case of any failure, please contact Audiomentors for
assistance.
THE CURRENT METERS
The two illuminated meters indicate the current supplies to
the four KT150 power tubes in the T-2000 25
TH
ANNIVERSARY.
Between and to the outside of each channel pair of KT-150’s
is a small toggle switch. Pushing the toggle toward the rear of
the chassis allows you to read and use the meter to bias the
rear KT150; pushing the toggle toward the front switches the
meter to the front KT-150. You can use the toggle during
operation.
There is a potentiometer for each . When you turn on the T-
2000 25
TH
ANNIVERSARY, the needle of the current meter for
each KT150 should be between the two parallel lines on the
meter face. Any error of current supply to or failure of a
KT150 tube is indicated by the needle on the meter moving
out from between these two parallel lines.
If a meter’s needle drops to the left limit of the meter’s face
during operation, this indicates a failure of the related KT150
tube. You must turn off the T-2000 25
TH
ANNIVERSARY and
replace both the fuse (0.5A, 250V, 20mm glass type) for that
tube and the KT150.
To replace a fuse, unplug the T-2000 25
TH
ANNIVERSARY; then,
using a screwdriver, simply turn the top of the fuse cap
counter clockwise. It will spring out holding the fuse. Replace
the fuse in the fuse cap, push the fuse cap down and turn it
