The Columbus will not recognize functions selected from the front panel.
Chapter Nine: Maintenance and Cleaning
9.1 Cleaning
Never use a wet method of cleaning the amplifier, i.e. 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.
9.2 Care
Be gentle with this amplifier. Any mechanical shocks and wide temperature changes,
moisture-rich environments and extreme conditions (dust, wind, heat, cold, moisture) can
substantially shorten tube life, in some cases, even 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 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. You’ll hate it if this happens, guaranteed!
