Specifications

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.

Note!

 The vacuum tubes are installed inside the device and should be replaced only by 

qualified service personnel.
