Always be sure the
speakers are plugged in before attempting to operate the amplifier. Severe
damage can occur from failing to connect the speakers to a tube amplifier.

NOTE:
Proper setting of the switch is critical for reliable operation.
To reduce the risk of fire or electrical shock, do not expose this unit to rain
or moisture. Do not operate your AT-112 near a pool or other standing
water. Make sure all blades on the polarized power plug are fully inserted
into the power source. Ensure the powercord is not stretched, pinched or
otherwise abused. Ensure the power cord is routed to avoid foot traffic.
Your AT-112 amplifier should be cleaned only with a dry cloth.
