Break-In
Your TAGA Harmony amplifier sounds great immediately after it is taken out of the
carton but as all hybrid 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.
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.
To replace the vacuum tube:
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. Make sure that the
vacuum tubes are cool.
4. The vacuum tubes are installed in sockets. Remove the vacuum tube you want to
replace by gently pulling it out of the tube socket.
5. Make sure to replace the vacuum tube with the same type or with another type which
is a direct equivalent of the factory installed one.
Gently but firmly place the new vacuum tube in the socket.
6. Before turning on the amplifier wait until the newly installed tubes reach the
temperature of the room.
