Replacing The Vacuum Tubes - Audio Note DAC One.1x. Manual

Use a cloth dampened with mildly warm water and a weak soap solution for removing
grease or oily substances. Strong or alcohol based solvents may cause damage to
the DAC's finish.
Replacing the vacuum tubes. The vacuum tube used in the DAC One.1x is a sub
miniature triode called the 6111WA, it is wire ended and soldered directly into the
PCB. The 6111WA should provide a useful life span of about 10 years if the DAC is
operated 24 hours per day, which is the recommended operation and the one that
sounds the best.
Although replacement tubes for the DAC One.1x are fairly widely available, better
performance will be obtained with tubes selected and matched specifically for the
DAC by Audio Note. Should the vacuum tubes require replacement, please contact
your Audio Note dealer for technical support.
