REPLACEMENT OF LOW LEVEL TUBES
All power must be switched off. Allow tubes to cool down. Remove the top glass cover. Remove
and replace with new tubes of the appropriate types, noting the location of holes in the socket and
pins of the tubes. Replace the glass cover before operating the amplifier.
Replacement tubes are available from VAC and other sources.

CARE OF CHASSIS
VAC chassis are machined aluminum for superior electromagnetic performance. The main chassis
is finished in nickel plating, which is kept waxed to prevent oxidation, staining, or discoloration of
the nickel. The power supply chassis is finished in durable textured gloss paint. Cleaning the units
with a damp cloth WHILE THE AMP IS SWITCHED OFF AND UNPLUGGED should suffice. Do not get
cleaning solutions onto or into the tube sockets. A light coat of wax should be applied periodically
to the nickel surfaces, taking care that the amplifier is cool and unplugged.
