MAINTAINING YOUR A 23	12

Your Parasound A 23 power amplifier requires no periodic maintenance and has no user-serviceable parts inside. To avoid the risk of electric shock, do not remove its top cover. The amplifier’s exterior can easily be cleaned with a soft cloth pre-moistened only with a few drops of water or glass cleaner.

Main Power Fuse

If this fuse blows, please contact Parasound Technical Service for further advice.
