You may use any KT150 type tube in the T-2000 25th Anniversary. Of course, you will have to adjust the
bias back into the area between the two parallel lines of the meter for a tube when it is replaced. Please
refer to Figure 8 for tube locations.

will prevent the new pair of KT150s from drawing too much current at first turn-on (not an uncommon
characteristic) and tripping the power fuse at the IEC connection. No harm is done to the original tubes
by turning the bias down, nor is any harm done to the new tubes by having them biased low to start.
Once the new tubes are installed and the T-2000 25
the bias so the needles for each meter are again between the two parallel lines on the meter.
If the current meter for one of the unit's KT150s has moved to the left of the parallel lines on the meter
face, using an appropriately bladed screwdriver, adjust the potentiometer directly in front of that tube's
location by turning it clockwise until the needle has returned to between the meter's parallel lines. If the
meter needle has moved to the right of the parallel lines on the meter face, turn the potentiometer
control counter-clockwise to correct.
As with all tube equipment, changing tubes from one manufacturer's to another's may alter the sonic
characteristics of the equipment.
All consequences of changing or attempting to change tubes are borne by the user unless by express
agreement between the owner and Allnic Audio or its authorized representative. Allnic Audio and its
dealers and authorized representatives are not liable in any way whatsoever for any injury or loss incurred
by the user or for damage to the T-2000 25

OPERATION
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 (refer to Figure 4). The remote control (refer to Figure 7) will also
control the input selections (using the number buttons or the buttons labelled "CH") and the volume
(using the buttons labelled "VOL" and "MUTE"). However, it will not control the power to the T-2000 25
Anniversary, which must be switched on and off manually as described above. Remove the screws on the
bottom of the remote control to replace batteries.
Pentode/Triode mode switching may be done "on the fly", that is, without muting or otherwise adjusting
your system's controls. Pentode mode provides more power. Switch between the two modes to determine
which you prefer. Your preference may apply all the time, or it may change for different types of music or
recordings. To switch between pentode and triode modes, use the button on the left hand side of the
front of the chassis. Button out is pentode; button depressed is triode (refer to Figure 4).
When you are finished listening, turn off your T-2000 25
