I'm another Newbie that needs help. The power supply for a Am10
pre calls for +/-28 vdc. The schematic shows a 36vct trafo. This
design uses a LM317 and LM337 regulators. Every 36vct trafo that
I find has a split secondary with 18v -center tap-18v. Do I need
to get a 56vct then have 28v center tap 28v? Or 72vct to get 36v center
tap 36v and then regulate to 28v? I'm real cornfused. Thanks for
any advice. fronk10
