”BURNING-IN” THE AMPLIFIER
Any tube amplifier requires an initial pre-heating (or "burn-in") period, in order so that it
achieves its full sonic potential. This is due to the presence of residua polarization of
dielectric elements and due to a necessary stabilization of working parameters of the
vacuum tubes. The stabilization of the electrical parameters of the system occurs in a natural
process whilst playing music through your audio system.
A preliminary degree of pre-heating of the amplifier is reached after about 10 hours of quiet
music playback.
The full sonic capabilities shall stabilize and unfold within a time-span ranging from
40 to 60 hours of music reproduction at a moderate volume levels.
In the initial period of operation of the amplifier it is advisable to avoid short-term
operation periods of the amplifier. Once activated, it should remain operational for a
period of about 4-6 hours.
REPLACEMENT OF THE VACUUM TUBES
Your amplifier is equipped with automatic bias module. It’s necessary to use PCL86 vacuum
tubes that have previously been pre-selected and paired up in quads.

VACUUM TUBE PROTECTIVE CAGE
The following picture show the correct positioning of the optional protective cage for the
tubes.
