To replace the vacuum tube:
1. Remove the tube cage – check “Tube Cage” for more details.
2. Make sure that the vacuum tubes are cool.
3. To protect the vacuum tubes during this operation, please put on the cotton gloves
which are supplied with this product.
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. If you change the output power vacuum tubes (EL34) make sure to “bias” your
amplifier – check “Vacuum Tube Biasing” for more details.
7. Make sure to reinstall the cage for the regular operation.
Vacuum Tube Biasing (EL34)
Only the output power tubes (EL34) need to be biased manually. This procedure
requires to open the amplifier and we recommend to contact TAGA Harmony
authorized service center to perform it.
Triode and Pentode Mode
Selecting the desired mode of operation for the output power vacuum tubes (EL34)
allows to modify the sound of the amplifier.
We encourage you to experiment with both modes and choose the most suitable for
your speakers and listening preferences.
Note!
Never perform this operation while the amplifier is turned on [turn off the
amplifier and remove the Power Cable] – it can damage this amplifier or speakers. This
may void your warranty.
Note! Make sure to select the same mode (Triode or Pentode) for both channels.
