Nice PSU! What is the final C value? Looks huge.

Hey X,
Happy Fathers Day!
The big caps are also 22,000uF, but 100v!
I had them from an old project.

L=Hammond 159ZJ,
C=22,000uF
38vdc loaded with Alpha BB
Itís extremely quiet, no noise at all from the speaker
Nice psu I know benefits of adding L, but never tried it. Those 3 paralled resistors are 3watters? Does they get even warm?

Yes they do!! Too hot, I will eventually replace them with a single .22R big watt resistor
Iím currently using a fan to keep them cool.
