Turn on the T-2000 30th 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 (see Figure 6). After about a thirty to forty
(30 - 40) second delay (the soft start), the T-2000 30th Anniversary will apply current to the power
tubes. The power button on the remote control, at its top left hand corner (refer to Figure 7), is
inoperative for the T-2000 30th Anniversary . It is normal for it to take a few minutes for the amplifier to
stabilize and the needles of the two meters to rise to their correct position (see the next section, below).
TUBES AND TUBE BIAS
The T-2000 30th Anniversary uses the following tubes:
•
Four (4) x KT170
•
Two (2) x 6J4
•
Four (4) x D3a
Because of the individual bias for each KT170, it is not necessary to use matched KT170 tubes in the T-
2000 30th Anniversary . You may use any KT170 type tube in the T-2000 30th Anniversary.
On initial turn on, you will have to set the bias for each KT170. Between and to the outside of each channel
pair of KT170s is a small toggle switch. Pushing the toggle toward the rear of the chassis allows you to read
the meter for the rear KT170 for that side; pushing the toggle toward the front switches the meter to the
front KT170. Using an appropriate screwdriver, you must turn the yellow potentiometer for each KT170 to
adjust the bias so that the needle is in the centre of the area between the two parallel lines of the meter.
Please refer to Figure 8 for tube and potentiometer locations.
If the needle of the current meter for a KT170 is too far to the left or outside to the left of the parallel lines
on the meter face, adjust the potentiometer adjacent to that tube’s location by turning it clockwise until
the needle is again in the centre 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.
You may need to repeat this process from time to time, and always when a KT170 is replaced.
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 30th Anniversary , any of its parts, or tubes or replacement tubes
resulting from the user changing or attempting to change
OPERATION
When the power is on, the current meters on the face of the chassis will illuminate. From this point on, the
T-2000
30th Anniversary’s operation is straight-forward. The face of the chassis has an input selector
