Installation
In your System
To insure normal component life and safe operation this unit must be
operated only in a horizontal (upright) position. Adequate airow and proper
cooling thereby can occur only if there is no restriction below, behind and
above the unit.
The four special non-marring elastomer feet provide adequate spacing only
from a smooth, hard surface. Never operate the unit while it is sitting on a
surface such as a rug or carpet.
If the unit is to be operated in an enclosed equipment cabinet, an exhaust
fan is desirable so as not to operate the VSi75 in overheated ambient air.
The “ambient” operating temperature should never exceed 120° F or 49°
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 amplier 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.
