How to Clean the Casework
If the 508 must be cleaned, use only a soft, lint-free cloth moistened with
plain water.
Never use any type of chemical cleaner unless recommended by your
dealer or the Boulder factory.
Do not use bleach! Bleach will remove the anodized surface of the case-
work.
Never use any type of abrasive to clean the casework.
If you have any questions, please contact your authorized Boulder dealer.
Placement and Installation
Your Boulder 508 Phono Preamplier is designed to reduce the effects that
external magnetic elds and radio frequencies (RF) have on its circuitry.
While placement is not critical, because of the high gain of the 508, known
magnetic elds should be avoided whenever possible. Power transformers
in other pieces of nearby equipment should be placed a minimum of 12
inches (30 cm) away.
Because it is heavy, the 508 must be placed on a sturdy, stable surface.
Do not place in an enclosed rack without ventilation. The 508 must have at
least 2 inches (5 cm) of airspace around the chassis for proper cooling and
airow.
Be sure to leave access to the AC mains and interconnect cables when
installing the phono preamplier. Depending on how easy it is to access
the back panel of the 508, it may be wise to pre-install the power and
interconnect cables before placement.
