I finally got around to finishing my PPA! I actually forgot all about it. I started it a long time ago so it was built on the V1.0A board. I guess they have since had 2 major revisions. Oh well....
So it powered up right off the bat and sounded pretty good. I prefer the sound of the OPA 627.637 mix. Just the 627 in all 3 channels was to laid back for me.
Had a bit of a problem doing the class A bias but i got help with that. Have them set to 2mA bias.
I will post some pics when i figure out how to post them.
For my next project I would like to build either the PPA V2 or an M3. Any thoughts?
