hello,
I want to build a ps wit lm317 and lm337 regulators.
the needed voltages are +/- 18V and +/- 15V
the transformer has 2 secondaries with 22V~
but I'm just aksing me where to connect the regulators for the +/-15V
in series after the +/-18V regulators??
or like the other regulators directly after the bridge rectifier??
thanks,
mat
