Switching on of the amplifier
On the front panel of the amplifier there are some red lights, which light up when You
switch on the amplifier to indicate the correct functioning.
The amplifier must be pre-heated at least for twenty minutes, to reach the right
temperature so as to get the best results in listening.
The cylinders of the transformer have the function of heat sinks of the system, so it's
normal that they reach a certain temperature during the listening sessions.
