Precautions and Maintenance

The Signature 284 requires no maintenance. It is, however, good electrical General Maintenance practice to clean all connectors once a year. An occasional dusting of the exterior

surface with a soft cloth helps maintain the unit's finish. Do not use any abrasive chemicals or cleaners as these will damage the surface.

Most tube amp problems are in the tubes themselves. A simple swapping of tubes can save a great deal of time, trouble and frustration. Although tube replacement is a simple procedure, it should be performed by experienced technicians.

The Signature 284 contains no user-serviceable parts.

Refer all service to qualified technical personnel.

Do not expose amplifier to moisture, rain, water, direct sunlight or extreme temperatures.

Connect amplifier only to an AC power supply that meets the specifications listed on the rear of the unit.

Always ensure that the amplifier is properly grounded.

Make sure that the amplifier has adequate air circulation near the rear vents.

To avoid damage to speakers and other playback equip- ment, turn off the power to all equipment before making connections.

Do not use excessive force in handling controls.

Remove the power plug from the AC mains if the amplifier is to be stored for an extended period of time.

Disconnect the AC Power Cord before removing the cover for service.

Avoid direct contact with heated tubes.
