hi!

a power supply problem...

i have a 2x18V/2.22A tansformer and after the bridge rectifier i get +/-
28V thus my +/-15V regulators get really hot (i know that the input of
the regulator should only be 3V higher than its output)
i suppose the 28V are not normal, are they?

(the rectifier is a 50V/6A one; i replaced it with 4 1N4005 diodes but
that didn't change anything)

any help concerning the +/-28V is really appreciated.

regards,
ulrich
