MAINTAINING YOUR SONAMP 1250 MKII
The Sonamp 1250 MKII does not require periodic maintenance and has
no user-serviceable parts inside. Do not remove the top cover as this will
increase your risk of electric shock. To keep the amplifier clean, use only
a soft cloth and never use any solvents or abrasives. Fingerprints may be
removed with a soft cloth moistened only with a few drops of water.
