i suppose i could be confused, but it sure looks like the LM337 and LM317 give you regulated + and - 17v
Dude... You can't get -17 -0- +17 from 7.5-0-7.5 taps (at least not on this PSU PCB)
It is Wrong, period!
in the edcore power transformer thread, you correctly mentioned that a
15/0/15 is a THIRTY volt transformer.
so if you use the center tap, you get THIRTY volts total.
I'm no electrical engineer but if you use the center tap and each secondary
into a full wave rectifier, you get +/-15v out of each side of the rectifier.
if you use a single NON center tap 15v secondary on a full wave rectifier,
you get +/- 15v out of either side.
I can't tell you how many cheap radio shack 12/0/12 volt transformers
i've used with the Mnats power supply board to get +/-24v.
have i imagined the +/-24v readings on my meter???
now, if there's the wrong VA rating, THAT would muck things up.......
