Break-in Period
Various components of the Tenor Phono 1 are burned-in for a period up to 200 hours
prior to being assembled. Each Phono 1 is further burned-in at the Tenor factory fol-
lowing assembly for a period of no less than 100 hours thereby allowing each electron-
ic component to stabilize and achieve its optimum electrical and musical equilibrium
as a system. Each phono stage is then calibrated to the factory specification and is
designed to remain within tolerance for a period up to 10 years or more depending on
use and care.
Tube Life
The Tenor Phono 1 is designed to operate within design specifications for a period
close to 10,000 hours.
As a typical example, a Tenor Phono 1 used each and every day for 3 hours under nor-
mal use will last almost 10 years before it will need a tube refit and calibration. Each
time one turns the Phono 1 on an elapsed hours clock is located on the Vacuum Flores-
cent Display (VFD), as shown below, during the startup sequence which exhibits the
owner’s hours total enjoyment to date. Most owners will experience a lifetime of lis-
tening pleasure without ever reaching the 10,000-hour maximum. When the 10,000
hours of use has been achieved, the phono stage should be returned to the factory for
re-tubing and calibration.
