Congratulations on your purchase of the Audio Note™ P-ZERO mono power amplifiers.
The P-ZERO’s are mono power amplifiers with an output power rated at about 8 watts.
We choose to use the now little used triode pentode ECL82 which was widely used in
small radios and early televisions as an output valve, the ECL82 is run in Class AB2,
which provides low-heat, reliable and long life.
Please read over this manual carefully in order to obtain the best possible performance
and longevity from the P-ZEROs.
UNPACKING & INSTALLATION
We recommend that you store the packaging materials in case the unit’s requires
shipping at a later date. Also, check that no transit damage has occurred before
installing the power amplifiers.
Next, select a suitable location for the units, ensuring that adequate ventilation is
provided, as some heat is generated by the power amplifiers during normal operation.
Worthwhile improvements may be obtained by locating the power amplifiers on a support
system specifically designed to reduce and absorb any vibrations.
AFTER CARE
Cleaning: No special maintenance is required for the P-ZEROs. A soft cloth or brush
similar to those sold by photographic stores for lens cleaning applications is best used for
cleaning.
Use a cloth dampened with a mildly warm, weak soap solution to clean off grease or oily
substances. Strong or alcohol based solvents may damage the finish of this amplifier.
Tube replacement: The output valves should be changed every three years if left on 24
hours a day, otherwise every 5-7 years.
Audio Note™ has taken considerable care in selecting and matching vacuum tubes
specially for the P-ZERO’s, and so we recommend that you contact your Audio Note
dealer, who will be able to provide the correct tube should replacement be required.
