MAINTENANCE:
Tube Replacement
When Should I replace a tube? This is a hard one to Answer as in this unit your tube
should last depending on its use for a very long period of time. If you hear unusual
sounds, squeals, or have low audio output, or distorted output, it is time to consider
replacing the tube. Your DARED Dealer may assist. Replace tubes always with the
same model number.
Regular Care
Keep the unit clean and free of dust.
Always turn of power and let the tube cool before cleaning the tube area and unit.
The vacuum tube may be removed easily with a gentle jiggle while lifting the tube
upwards out of its socket. Use the same method when reinstalling the tubes. Only
touch when cool.
When cool the vacuum tubes may be cleaned with a soft and slightly dampened
microfiber cloth.
The case may be cleaned with a slightly sampled microfiber cloth and then polished
using a separate dry soft microfiber cloth.
