Well guys, Heres the problem. I turned the amp on this morning and nothing happened. Transformer does not even make sound once connected. Maybe I just can't here it tough. It did it more than once in the past but now I think it was the last time, hes gone .
What can I do to solve my problem ? Change the transfo?

Do you measure continuity through the transformer primary ?.

Check for Dc offset at the output before the relay - if you have DC you have a blown output stage that needs rebuilding.

Dry joints are another cause and if so, open it up and blanket resolder the power supplies, regulators and output stages.
