Some important tips for sizing secondary windings::

1) If you want to make a DC power supply with 4 diodes and know the output DC current, to correctly size the secondary of the transformer you need to multiply the DC current by 1.4.

Fig. 1


2) If you want to make a DC power supply using a secondary with 2 diodes and a central tap as in the fig. shown below, you must multiply the DC current by 1.4 but consider that the two branches of the secondary will work in parallel , so the result should be divided by two.

Fig. 2


3) If the central tap of the secondary is used to directly supply alternate, for example, the filaments of thermionic valves, the current must be indicated without modifications.
