THE PROBLEM
PROBABLE REASON
THE SOLUTION

position, the amplifier does not switch on.
A blown fuse
Please exchange to faulty fuse to a new one
(3,15A T), within the fuse holder as
depicted with index 4 on page 8 of this
user’s manual.
An improper connection of the mains cable

are properly inserted into the electrical
mains socket and to the socket as depicted

distorted. A hum or pops have appeared
and are coming from one of the channels.
An improper placement of the vacuum
tubes in the sockets

orientation.
One of the tubes (PCL86) has lost its
nominal working parameters
