PRECAUTIONS
TUBES ARE HOT! Make sure you allow the tubes in your amplifier to cool down before
handling them. They are also made of glass and can easily break. Wear safety gloves and goggles
when handling audio tubes.
DO NOT OPEN UP THE AMPLIFIER! There are no user serviceable parts inside. There are
lethal voltages present even when unplugged.
NEVER: replace the Mains or H.T. fuse with a higher rated fuse. This will most certainly cause
severe damage to your amplifier.
NEVER: use a shielded guitar or instrument cable as a speaker cable connection.
NEVER: operate any amp without a speaker load connected to the output jack .

manual.
ALWAYS: use a three pronged, grounded AC power cable and always plug into a properly
grounded outlet. Failure to do so may result in injury or death.
ALWAYS UN-PLUG YOUR AMPLIFER WHEN YOU ARE DONE! This is to protect your
amplifier from surges in electrical power, or transient voltage. The standard American home AC
voltage is 120 Volts. Anything over this amount is considered transient and can damage
electronic devices that are plugged into an AC outlet. Though power surges are brief and
measured in nanoseconds, they can cause considerable or permanent damage to electronic
equipment. Electrical surges can damage electrical equipment by burning or fusing internal wires
or by the gradual degradation of a device's internal components. The best way to prevent
damage is to unplug your amplifier when not in use.
NOTE: Devices such as refrigerators and air conditioners require large amounts of energy to
switch motors and compressors on and off. Such devices can create surges in power that disrupt
the steady flow of line voltage. Lightning, faulty wiring, downed power lines and faulty
equipment at the power source can all cause power surges as well.

ALWAYS: try to keep your amplifier and /or speaker cabinet in a climate controlled setting.
Failure to do so can be problematic. The tolex on your amplifier head box cabinet can shift and
shrink in the Summer, especially if you leave your amplifier for an extended amount of time in a
sun heated vehicle, trunk, trailer, or an extremely hot and humid, non-airconditioned
environment. This is due to the glue used to apply the tolex to the wooden head box cabinet. The
glue can become slightly molten from excessive heat, which can make the tolex movable, expand
and then shrink when cooled. Excessive heat can only cause this tolex situation and this is not
covered under your Komet warranty.
