Important Information:

1. Please read all of the information contained in this document.

2. HUM - Some hum or amplified noise is normal. As the volume is increased

some amplified noise may be noticeable and will be more apparent in a small
quiet room. Additionally, tubes have inherent noise as do resistors. However,
excessive hum (noise) can be caused by electronic devices located near the amp
or on the same circuit such as neon signs, fridges, fluorescent lights, computers,
light dimmers, aquarium pumps, etc. Hum can vary with different outlets,

rooms or buildings.

3. Do not operate this amp without a speaker load.

4. This amp is equipped with a 2A thermal circuit breaker instead of a fuse. If a

problem develops with the amp, the circuit breaker will open and the amp will
not operate until the circuit breaker is re-set. The circuit breaker is located on
the bottom of the amp chassis behind the rectifier tube. After re-setting the
circuit breaker, if the amp does not operate or continues to pop the breaker, the
amp needs service.

CAUTION

RISK OF ELECTRIC SHOCK

WARNING: This guitar amplifier contains lethal HIGH VOLTAGE. To avoid risk of
injury or death from electric shock, do not open the enclosure or remove the back cover
from the amplifier. Refer all service work to qualified personnel.

WARNING: This amplifier contains Vacuum Tubes. Vacuum tubes are heated to produce
electrical currents and they get HOT. Touching this surface could result in bodily injury.
To reduce the risk of injury from a hot component, allow the surface to cool before
touching. DO NOT touch or attempt to remove vacuum tubes until they have had time to
cool.

Care should be taken so that objects do not fall and liquids are not spilled into the enclosure
through openings.

POWER SOURCES: The amplifier should only be connected to a 120VAC household
power source.

GROUNDING OR POLARIZATION: Precautions should be taken so that the grounding or
polarization is not defeated. Do not remove the ground from the power cord.

POWER CORD PROTECTION: Power supply cords should be routed so that they are not
likely to be walked on or pinched by items placed upon or against them, paying particular
attention to cords at plugs, convenience receptacles, and the point where they exit from the
amplifier.

SERVICING: You should not attempt to service this amp beyond that described in the
operating instructions. All other servicing should be referred to qualified service personnel.

FUSING: Your amplifier is equipped with a thermal circuit breaker located on the bottom
of the chassis behind the rectifier tube.
