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.
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 a durable clear powdercoat paint. Cleaning the unit 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 or jacks.
