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 A-2000 SE and replace both the fuse (0.5A, 250V, 20mm slow-blow) for that tube

and the KT150 itself. To replace a fuse, using a screwdriver, simply turn the top of the fuse cap counter-clockwise. It

will spring out holding the fuse. Replace the fuse, push the fuse cap down and turn it clockwise; it will lock itself. If

you have any questions about doing this, please contact Your Allnic dealer for assistance.

If the AC mains fuse, located at the IEC input, has failed, it can be replaced with the spare fuse (5A, 250V, 20mm

slow-blow) provided in the tray in the IEC mount. Again, if you have any questions about doing this, please contact

Your Allnic dealer for assistance.

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. When replacing a KT150, first turn the bias screw counter-clockwise slightly to reduce current,

in case the bias is set too high for the new tube (since the old tube may have required additional bias). Bring the

bias up gradually to the middle between the two lines on the meter.

All consequences of changing or attempting to change tubes are borne by the user unless by express agreement

between the owner and an authorized Allnic 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 A-2000 25

Anniversary SE, any of its parts, or tubes or replacement tubes resulting from the user changing or attempting to

change tubes.
