In your system
To insure normal component life and safe
operation this unit must be operated only
in an upright position. Adequate airflow and
proper cooling can occur only if there is no
restriction above and behind the unit and on
either side.
The special non-marring elastomer feet
provide adequate spacing and stability
only on a smooth, hard surface, and also
assist to isolate the amplifier from spurious
vibrations. For upright stability and best
performance, never operate the unit while it
is sitting on a soft surface such as a thick rug
or carpet.
Due to its weight, this amplifier must be
supported on a surface specifically rated for
such a load. Check with the manufacturer of
your support system to be sure it is rated to
handle this weight.
If the unit is to be operated in an enclosure
such as an equipment rack, make certain
that adequate airflow above and to each
side of the unit is provided.
The ‘ambient’ operating temperature should
never exceed 86° F or 30° C. Improper
installation will cause premature tube failure
and will affect your warranty, as well as the
service life of the unit.
It is normal for a vacuum tube power
amplifier to run quite warm, and if used
for prolonged periods, hot to the touch. All
components within are, however, operated
at safe, conservative levels and will not be
improperly affected thereby, providing the
requirements outlined above are adhered to.
A Note about Vacuum Tubes
The vacuum tubes in your Reference 150 SE
have been burned in, tested and electrically
matched to provide the best performance
and reliability of your amplifier. That said,
vacuum tubes must be replaced from time
to time. The KT150 output tubes in the
Reference 150 SE should have an expected
life of approximately 3,000 hours, while
the smaller 6H30 tubes should have a life
expectancy of approximately 4,000 hours.
These life expectancies are only approximate.
