Life Span - Diezel Einstein Owner's Manual

5.2.3 Life Span

Power tubes last 1 to 3 years, depending on care, volume and frequency of use of the
amplifier. If you use your amp only once a month, then the tubes will last much longer. Really.
We have heard tubes that are over 10 years old, but it was not a good thing. Tubes age very
slowly; slow enough for the artist to get used to the changing tone. To keep things fresh, and to
keep your tube dealer in business, we recommend re-tubing, cleaning and biasing once a year if
the amp is used frequently.
Chapter Six: Layout of Controls
6.1 Manual Channel Selection
The 2 channels of the Einstein can be selected manually by activating the select switch for
either channel. Alternatively, a foot switch can be connected to remotely control the channel
selection.
6.2 Master 2 On/Off
Master 2 can be used for all channels, and can also be remotely controlled via the included
foot switch. This allows instant volume boost, or cut, without fiddling with the amp. Once
adjusted to suit your needs for the gig, it's a thing of pure beauty. You can select the Master 2
function via the Diezel 2-button foot switch. Actually, you can also use a readily available
single button foot switch with a 1/4" connector.
6.3 Channels
• Channel One
Control perimeters include Gain, Volume, Treble, Mid, and Bass. A 3-position toggle switch
selects preset gain modes.
• Channel Two
Control perimeters include Gain, Volume, Treble, Mid, and Bass. This channel can be selected
via the toggle switch, or via the Diezel 2-button foot switch.
6.4 Effects Mix control Rear panel
This control determines the amount of effect signal in the parallel loop
Chapter Seven: Maintenance and Cleaning
7.1 Cleaning
Never use anything wet to clean the amplifier, any amplifier. Usually, it is sufficient to wipe
down the outside of the amp with a slightly moist cleaning rag. Do not use abrasive cleaning
chemicals. Sometimes a vacuum cleaner can be used to remove dust and dirt from nooks and
crevices. Do not remove the chassis from the housing to clean the amp; the inside of your amp
carries dangerous Voltages.
