Печатать страницуcorner (refer to Figure 4), is inoperative for the T-1800 Mk2. Remove the screws on the bottom of the remote
control to replace batteries.
When you are finished listening, turn off your T-1800 MK2 stereo amplifier(s) first; then, turn off your preamplifier
(if using one) and sources. In the case of any failure, please contact your Allnic dealer for assistance.
THE CURRENT METERS
The two illuminated meters indicate the current supplies to the four EL34 power tubes in the T-1800 MK2. Between
and to the outside of each channel pair of EL34s is a small toggle switch. Pushing the toggle toward the rear of the
chassis allows you to read and use the meter to evaluate the current condition of the rear EL34; pushing the toggle
toward the front switches the meter to the front EL34. You can use the toggle during operation. See Figure 5.
When you turn on the T-1800 MK2, the needle of the current meter for each EL34 should be between the two
parallel lines on the meter face. Any error of current supply to or failure of an EL34 tube is indicated by the needle
on the meter moving out from between these two parallel lines.
If a meter's needle drops below the left parallel line during operation, it indicates a failure of the related EL34 tube.
You must turn off the T-1800 MK2 and replace the EL34. Check the meter for the other EL34 on that channel. If the
meter needle is between the parallel lines, it is not necessary to replace that tube.
If you have any questions about doing this, please contact your Allnic dealer for assistance.
TUBES
The T-1800 MK2 uses the following tubes:
• Four (4) x EL34
• Two (2) x E180CC
• One (1) x 12AY7
Because of the automatic bias for each EL34, it is recommended to use closely matched pairs of EL34 tubes in the
T-1800 MK2. Please refer to Figure 5 for tube locations.
You may use any EL34 type tube in the T-1800 MK2. However, as with all tube equipment, changing tubes from
one manufacturer's to another's may alter the sonic characteristics of the equipment. It is NOT recommended to
substitute the EL34s with power tubes commonly considered similar to them.
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 authorized
representatives are not liable in any way whatsoever for any injury or loss incurred by the user or for damage to
the T-1800 MK2, any of its parts, or tubes or replacement tubes resulting from the user changing or attempting to
change tubes.
