4.1 Vacuum Tube Care and Maintenance
Your TubePre V2 is equipped with a 12AX7 vacuum
tube. This tube works well in a wide variety of situations;
however, some owners may wish to experiment with
other compatible vacuum tubes to explore additional
tonal possibilities. There are many different 12AX7 tube
brands from which to choose but you must use a 12AX7.
Tube life and performance are affected by how often
the tube is used and how hard the tube is driven
while in use. Poor performance and microphonics
(noise caused by mechanical vibration of the elements
of an electron tube, component, or system) are the
most common signs of wear. Periodic replacement
of the vacuum tube is recommended. There is no
predetermined time for replacement. If you notice that
the sound quality in your TubePre V2 has deteriorated,
it is most likely that a worn out tube is to blame.
