Maintenance
The DAC215 is built for a long lifetime and no special care needs to be taken, except from
what is already described under installation. However, the heart of the amplifier is the tubes,
and like a light bulb, they have a limited lifetime. After a period of time, they may affect the
performance of the amplifier. The tubes are operated around 20% of their full nominal power,
which considerably increases their life expectancy. The lifetime of the tubes should be at least
6000 hours, assuming that the player is switched on and off a couple of times per day.
Backlight
The red backlight of the tubes can be turned off and on by a slide switch located inside the
DAC215 at the vertical red circuit board just behind the tubes. The switch is small and you
might need something like a toothpick to operate it.
The back light is on when the switch is in the upper position and off in the lower position.
.
Fuse
The DAC215 employs a 20 mm glass fuse circuit breaker inside the IEC-AC socket at the
back. The fuse value is 0.5A (1A for USA)
Warranty and Service
Copland provides a warranty to the first purchaser for a period of two years. Copland usually
commissions the Copland agency in the country in which the amplifier was purchased to carry
out any warranty work.
Following consent from Copland in a particular case, the warranty service may also be
claimed at an agency in another country.
