Safety Notes:
This is an electric audio device that uses a mains power adapter and vacuum tubes. Use only the specified 12 V / 1.5 A adapter and an appropriate mains voltage (AC 110–240 V). Unplug the unit before cleaning or servicing. Do not expose the unit to moisture or liquids.
Vacuum tubes get hot during operation. Allow tubes to cool before handling or replacing. Only replace tubes with the correct type and follow proper ESD and handling precautions. Do not open the chassis or attempt internal repairs—risk of electric shock. Keep out of reach of children.
