MAINTENANCE AND CLEANING
The THA2 usually requires no maintenance. Please contact your Goldmund approved
dealer if any maintenance should be required.
Always turn the power OFF before cleaning your THA2. To clean the external metal of the
amplifier, always use a clean, soft, damp cloth. Dampen it with water or a mild detergent
solution. Avoid abrasive or harsh cleansers (e.g. products containing sodium carbonate).
The identification plate is plated with precious metal. Simply clean it with a soft cloth,
without any chemical solution.
