Additional information
Break-In
Your TAGA Harmony amplifier sounds great immediately after it is taken out of the carton
but as all tube/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.
Tube Cage
For your safety and to protect the vacuum tube 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 tube.
When the cage is removed - do not touch the vacuum tube - it 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 tube.
4. Remove the cage by pulling it in upward.
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. Remove the tube cage – check “Tube Cage” for more details.
2. Make sure that the vacuum tube is cool.
3. The vacuum tube is installed in a socket. Remove it by gently pulling it up out of the
tube socket.
4. 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.
5. Make sure to reinstall the cage for the regular operation.
