Break-In
Your TAGA Harmony amplifier sounds great immediately after it is taken out of the
carton but as all vacuum tube amplifiers, this amplifier requires a “break-in” period to
reach its full sonic capabilities.
During the “break-in” period it is recommended to operate the amplifier at moderate
volume levels.
The first level of the “break-in” is reached after approximately 10 hours of play.
The optimal level of the “break-in” is reached after approximately 40 to 60 hours of play.
It is recommended to avoid one-time short periods of operation unless the amplifier
reaches the first “break-in” level. When the amplifier is turned on, it should operate for
around 4-6 hours.
Turn off procedure
Make sure to turn off the amplifier first when powering down your system.
Note!
If the amplifier was turned off even for a short period of time, you should wait
at least 2 minutes before turning it back on. Do not turn it ON then OFF and then ON
again in quick succession.
Follow this procedure each time you turn your amplifier OFF / ON. This precaution will
minimize the stress (high voltages) on internal components.
Tube Cage
For your safety and to protect the vacuum tubes this amplifier is equipped with the
vacuum tube cage which is factory installed.
It is not recommended to remove the cage unless it is required to change the vacuum
tubes.
When the cage is removed - do not touch the vacuum tubes - they may be hot and
burn the skin!
To remove the cage:
1. Turn off the amplifier.
2. Unplug the Power Cable from the electrical outlet.
3. Wait for approximately 30 minutes to cool down vacuum tubes.
4. Remove the cage by pulling it in upward.
Make sure to reinstall the cage for the regular operation.
Vacuum Tube Replacement
The lifetime of vacuum tubes may vary and depends on their operation time and
ambient temperature, playback volume levels and the number of on and off cycles.
Note!
The warranty time for vacuum tubes is shorter than for other components of this
device - for more details check your warranty terms or contact a local dealer.
Replacement vacuum tubes are not supplied with this product.
