One of the key features of the DUALKLONZ is the possibility to use many different
power tubes, without the need of any setting.
The following tubes can be used:

Please note that, when using 6V6 or EL84 tubes, the rated impedance of the
speaker outputs is doubled.
The stock tubes are 2 6L6s. 2 EL84 and 2 EL34 power tubes will be included,
therefore you can change power tubes according to different amp tones.

Changing power tubes
Switch off the STANDBY switch and the main On/Off switch. Remove the mains
power cord from the back of the amp. Let the tubes cool down for at least 10
minutes. (Please make sure the tubes are not too hot to hold)
Remove the back grille.
Push the metal clamps down with two fingers and remove the power tubes by
gently pulling and tilting them.
Insert the new tubes: first check the alignment of the pins, then gently push
the tube in place. DO NOT force the tubes. If you encounter some resistance,
re-check the pins straightness and alignment.
Re-install the back grille.
Proceed with the standard switch-on procedure according to the typical setup
and cable connections.
