4. TION Please read and follow all ofthe safety information to prevent personal injury and damage to the equipment Do not expose the amplifier to rain moisture or other liquids to prevent damage fire or electrical shock Unplug the power supply cord from the wall outlet before servicing including removing and adding vacuum tubes and fuses to prevent electrical shock Vacuum tubes become very hot when operated Allow adequate time for the tubes to cool before replacing them to reduce risk of personal injury This amplifier is capable of producing extremely high noise levels which may cause temporary or permanent hearing damage Use care when setting and adjusting volume levels during use This amplifier should be serviced by a qualified service technician when the power supply cord or plug is damaged liquid including rain has fallen onto the amplifier the amplifier does not operate normally or the amplifier has been dropped to prevent personal injury or further damage to the amplifier CAUTION Only connect the power supply cord to an earth grounded AC receptacle rated for 120 V 60 Hz to prevent damage to the amplifier CAUTION Do not defeat the safety purpose of the grounding type plug Ifthe plug does not fit into the outlet contact an electrician to replace the obsolete outlet to prevent damage to the amplifier CAUTION Do not operate the amplifier without a speaker load to prevent damage to the amplifier CAUTION Do
