The amplifier is build for a long lifetime, and no special care needs to be taken apart
from what is already described under installation. However the heart of the amplifier
is the Valves / Tubes and like a light bulb, they have a limited lifetime and can therefore
after a period affect the performance of the amplifier. You should therefore after 4000
playing hours, or if the amplifier changes sound, contact your service agent for replace-
ment of valves.
