2.1.4 Operating Temperature
It will take a little more time after warm-up until everything inside the amp is working in
sync and to its fullest potential. A trained ear will notice a slightly warmer tone and better
complexity in tone after playing the amp for a short while. It’s like warming up before
running a marathon. Get it?
2.1.5 Power Tube Life
The power tubes of your amplifier are subject to a certain aging process. Once one of the
tubes shows signs of aging, unreliability or unusual noise, then we suggest that you
replace all power tubes. Matched tube sets wear relatively even, or so our experience
suggests. This means if one goes, the others are not far from meeting the same fate.
The aging process manifests itself by a depletion of a thin layer of Wolfram on the Anodes.
This can take anywhere from 6 month to 3 years, depending on the amount of use of the
amplifier. The amount of wear is determined by the amount of performance that is asked
from the tube.
