Default 'lytic and PSUd question

convenient values for resistance in PSUd II for 33.000Uf and 22.000UF?

I presume that
1/(2xPi x 2x50Hz x C)

is best case?

anyway-look:

Hi,

I don´t think you may use that formula to calculate ESR.

Your PSU looks nice but how did you make a 9mH / 0,2 Ohm choke?

9mH seems a bit overdone, normally 2-3mH is OK.

seems that I must look for some datas for ESR....

chokes are from old cinema projector PSU for sound bulbs (lamps)
EI 72 iron, n original PSU worked at 5A

I have exactly two-perfectly adequate for 4A for Babbelfish J

anyway-look:
At power supply frequency that would be the Capacitive Impedance, Xc, in series with the cap's ESR.
