Wait at least 60 seconds before raising the volume. The tubes require this time to reach stable operating temperature. Optimal acoustic performance is usually achieved after 20 to 30 minutes of thermal stabilization. Powering Down Protocol Turn the DA30 volume completely down. Switch the power toggle to the OFF position.
Check the main fuse located next to the power cord inlet. If the internal wire is broken, replace it with a fuse of the exact same rating (see back panel for value). Hum or Buzzing Noise

The DA30 uses fuses to protect its critical and expensive components, like the output transformers. The most common fuse is the located on the primary side of the output transformer. If a fuse blows, it's a strong indicator of an underlying issue.
