Greetings to all users
I write from Italy, here there are many threads of this amplifier, which I preferred at the time than the Onkyo or Luxman, after about 25 years of work, piloting two ESB and now two Boston Acustics, switches had to be reviewed , and the right channel had stopped working. A technician has fixed switches and said he had also arranged that the non-functional channel. He said he checked the output signals with the oscilloscope and who were perfectly identical, but the repaired channel actually has less than half the power compared to the other channel (the left). I recovered the service manual with circuit diagrams and I would fix it myself, perhaps with the help of someone in the forum.
Any advice would be welcome. Thank you
