VAC Signature Preamplifier Mk I - Manual (Page 10)

CARE OF CHASSIS
VAC chassis are machined aluminum for superior electromagnetic performance, and finished
in durable textured gloss paint. Cleaning with a damp cloth WHILE THE AMP IS SWITCHED
OFF AND UNPLUGGED should suffice. Do not get cleaning solutions onto or into the
connectors or controls.
When shipping your unit, be certain to wrap the amplifier in the cloth, tissue or plastic wrap
in which it was originally packaged. Given the high gloss of the lacquered finish, make sure
there are no ridges or sharp surfaces in those parts of the cloth which contact the faceplate.
Use of a coarser cloth or failure to otherwise protect the faceplate may result in damage to
the finish. VAC is not responsible for cosmetic damage resulting from improper care or
packing.
A Word About Tubes in General
Tubes are like the tires on a car; they will eventually need replacement. Murphy’s Law states
that a tube will probably fail right at the start of a long holiday weekend. Therefore, many
audiophiles keep a spare tube of each type on hand, just in case!
VAC can test tubes for concerned customers.
