SERVICE AND CARE ________________________________________________
The chassis may be cleaned with a soft towel and Windex® or a similar window cleaner. Spray it on the
cleaning cloth to moisten it, not on the component. Do not use solvents or harsh chemicals to clean the
preamplifier. They may remove the labels from the chassis. The frequency and need of cleaning will be
governed by operating environmental conditions. Avoid letting the component become dusty or wet. A
‘feather duster’ type cleaner will also work well for cleaning the component.
