Hey all,
I'm working on my first amp design. I want to do a combination RIAA-equalized phono preamp and headphone amp. I want to be able to listen to my turntable in a discreet area without having a large stereo receiver around.
The goals for my project are:
- Small, portable enclosure
- Able to run off wall power or batteries
- Built in battery charger
- Flexibility for future modifications
My basic design is a combination of this mini phono preamp: http://www.diyaudio.com/forums/analog-line-level/79545-mint-tin-phono-amplifier.html
With Tangent's CMoy: http://tangentsoft.net/audio/cmoy-tutorial/
I'm using several other Tangent circuit designs, including his virtual ground channel PSU and battery trickle charger.
I've got hand-drawn schematics for most of it, but for now I just want to share my power supply schematic and see if I'm on the right track. I'm VERY new to electronics but I'm trying to take the design process slow to make sure I understand what everything does and why. My dad is an electronics whiz and has given me a lot of great info and guidance so far, and I'm trying to apply that to my first solo build.
If you have time to look this over and give me some feedback that'd be great!

I'll post the actual amp schematic at some point soon...
Thanks for looking,
