Is the trafo vibrating? Did you glued the core?
Yes. I glued too.
I'll try to point the effects and the circunstances:
- Using inductor before output capacitors, I only get HISSSS when I drain a lot of current, but, the problem is that the voltage drops A LOT, like, from 48 to 40 even with a small load (50w).
- Without inductor, when I apply load, the voltage RISES. I used original EI33 from ATX PSU, first it was 42v, with load it rose to 47! With more load it went to 52 almost blowing up my capacitors. And HISSING.
The trafo that was vibrating with no load was too strong, like only 28 turns on the primary. With the other only vibrates with load.
