Chapter Seven: Maintenance and Cleaning
7.1 Cleaning
Never use anything wet to clean the amplifier, any amplifier. Usually, it issufficient 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 usedto 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.
7.2 Care
Be gentle with this Amplifier. Any mechanical shocks, extreme temperature changes,
damp environments, and other extreme conditions (dust, wind) can substantially
shorten tube life. In some cases, even the amplifier life. Do not block the air
circulation grilles in the front and in the back of the amp. Do not push the amp right
up against objects that would interfere with its normal airflow. The top of the
amplifier might get warm after a prolonged use; this is normal, but will melt your ice
cream and definitely ruin your beer. Never put beverages on top of the amp where
they could spill and flow inside the amplifier. Will you rue the loss of your beverage
first or the loss of your amplifier?
7.3 Tube Change
Tube changes are only to be performed by authorized service personnel. If power
tubes with different values than the stock tubes are to be installed, then the amplifier
must be re-biased before operation can be resumed. The amplifier uses atwo circuit
bias system. It is quick and easy to accomplish biasing but were commend that you
refer to trained professionals to attempt this procedure.

congratulate you on your decision to purchase the Diezel
Einstein Amplifier.
