Cleaning

To  maintain  the  visual  appearance  of  your  PH5    phono 
preamplifier,  occasionally  wipe  the  front  panel  and  top 
cover surfaces with a soft damp (not wet) cloth to remove
dust.  A  mild,  non-alkaline  soap  solution  may  be  used  to 
remove  fingerprints  or  similar  smudges.  Cleaners  contain-
ing abrasives should 

not

be used as they will damage the

“brushed” grain of the front panel finish. A dry 2-inch pure
bristle paint brush works well to remove dust from bevels,
reliefs and switches.
