If a meter's needle drops to the left limit of the meter's face during operation, this indicates a failure of the related

KT170 tube. You must turn off the M-3000 MK 3 and replace both the fuse (0.5A, 250V, 20mm glass type) for that

tube and the KT170. To replace a fuse, using a screwdriver, simply turn the top of the black fuse cap

counterclockwise (See Figure 6). 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 provided in the tray in

the IEC mount (See Figure 5). You MUST unplug the M-3000 MK3 to replace an AC mains fuse. 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 KT170, first turn the bias screw counterclockwise 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 M-3000 MK 3, any of

its parts, or tubes or replacement tubes resulting from the user changing or attempting to change tubes.
