First, I'd like to thank everybody in DIYAudio. I've been digging around on the site for a while - looking for ideas, and getting quite a few.
I'm getting ready to breadboard this design for a regulated mixing console power supply. For the console in question, the supply will need to provide +/-15v at 1.5a per rail, +10v at 1a, and, of course, +48 up to about 0.3a. I want it to have plenty of current headroom above those values. Please take a look, and tell me what you think. Thanks in advance! |

I think you should use two windings and two Bridges for the +/-15V supplies.
Then you can you can use two LT1085 (or LT1086) which are much better than 317/337 types. (Amek did this with LM338's and pass transistors) For the +10V same thing,If you must tap off for +10V come off the + supply bridge. Otherwise I would use another winding. Same applies for the +48V supply. TL783 are fine, I use a 120-330 ohm R in series with each mic socket. After the R I use a 10-22 mfd 100V cap. Lowers the noise a bit. |
