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
temperaturechanges, damp environments, and other extreme
conditions (dust, wind) cansubstantially 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. Donot push the amp right up
against objects that would interfere with its normalairflow. The top of
the amplifier might get warm after a prolonged use; this isnormal,
but will melt your ice cream and definitely ruin your beer. Never
putbeverages 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 powertubes with different values than the stock tubes are
to be installed, then theamplifier 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 werecommend that you refer
to trained professionals to attempt this procedure.
