Hi everyone.
What could be the reason linear PSU to output higher than its rated voltage?
I have two 12V psus which output 18vDC ( 16vDC with load ) and 22vDC ( 18vDC with load ).
Both 470uF filter caps are fine ( capacitance and ESR ).
On the secondary transformer side I get 14 and 17 vAC.
Diode bridge rectifiers.
