face, turn the potentiometer control counter-clockwise
to correct.
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 M-3000 MK2
and replace both the fuse (0.5A, 250V, 20mm glass type)
for that tube and the KT150. 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 Audiomentors for assistance.
You may use any KT150 type tube in the M-3000 MK2.
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 6 for tube
locations.
All consequences of changing or attempting to change
tubes are borne by the user unless by express
agreement between the owner and Audiomentors.
Allnic Audio and Audiomentors are not liable in any
way whatsoever for any injury or loss incurred by the
user or for damage to the M3000 MK2, any of its parts,
or tubes or replacement tubes resulting from the user
changing or attempting to change tubes.
