Many thanks Onno and Maurice.

Maurice, i don't have a wave generator
At this moment a don't have more BC337 to check. Meanwhile I tested the ua741 and it is OK, and all the resistors and condensers (again). The tensions are all correct.
I removed the transformer, measured it and it looks ok. There are no signs of being shorted.

Regards
Carlos
