Also, you may want to check or replace the UF "ULTRA Fast" diode in that
circuit. I found some that developed a leak but not enough to short and
pass some AC through from the switcher.. This can not only heat the
diode but the Cap. A simple test is to perform a thermal test on the
diode.. It should only be warm at best..

Good point, the diode gets very hot, too. Will try to replace it.

Thank you to all.
