Cleaning the unit should take place only when it is
switched off and the valves are cold.
Use a soft dry cloth. Do not use solvents or alcohol based
detergents.
Do not rub hard when cleaning the printed lettering.
Never operate the unit if it is covered!
Never attempt to remove the valves when the unit is
switched on!
If you need to remove and replace the valves, do so only
when the valves are cold and the unit is switched off, and the
AC cable has been unplugged from the amplifier.
Replace valves only with others of the same type, preferably
in matched pairs.
Avoid shocks and vibration to the unit, which can damage
or reduce the life of the valves.
