someone has idea what kind of noise could generate a regulator, if input voltage is not sufficient?
I have a power supply with 12V AC rectified and regulated with a 12V regulator. the voltage drop a lot due the cheap transformer and I´m having 12V not 13V so the regulator is not working.
I´m having some spikes and a lot of harmonics 100 ,150,200,250,etc.
I think that it can be contaminating the ground of the circuit which is common . I have this noise on the B+ and on the output.
I know that I must remove the regulator, I just want to know if somebody has experience with this kind of noise.
the power supply is for 2 12ax7 heathers.
I have 6600uF before the regulator and 47uF on the output.
