Hi friend. check the main filter of the source may be devalued and check the filters that are after the choper may be dry. regards
Good evening, dear colleagues. First of all I apologize if I was discourteous to take a moment to respond to your suggestions, but just the day after asking the question, I ran out of Internet, until today it has been restored.
Regarding the subject, I tell you that I already solve the fault. so checking the capacitors of b + when I remove them to measure them and install them again, I find the surprise that now I did not have any voltage in the secondary, then I told myself this is welding. and proceeded to review all the primary of the source.
and the new surprise was that the voltage appeared and the tic tic disappeared. In short, the fault was false welds in the primary of the source.
Thank you very much for having your time to help me.
