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. Note that these tubes have a central platic
shaft with a locator ridge on one side; this ridge must be aligned with the slot in the socket. Replace
the glass cover before operating the amplifier.
The exact characteristic of each tube and the relationship among the five 6SN7 is critical to the
optimal performance and best sound of your amplifier. Therefore we recommend obtaining
replacement tubes from VAC, specifying that they are for use in the Statement 450 amplifier.

CARE OF CHASSIS
VAC chassis are machined aluminum for superior electromagnetic performance. The main chassis and
the fascia are finished in an acrylic lacquer, similar to fine automobile; similar care must be taken in
wiping or cleaning. THE AMP MUST BE SWITCHED OFF AND UNPLUGGED, and at no time may any
cleaning material be allowed to get into the tube sockets or jacks.
