And where to solder on v1 board please?

You don't.

You send it back for a Rev 2 replacement that has already been fixed.

Re: Super SD System 3 Audio Buzzing

So 10uF, but what voltage on that cap? (I always screw up the ratings on these when I'm trying to figure it out - think the uF needs to be exact but the voltage can be whatever as long as it's higher rated than the original, right?

I installed the FBX mod.

Nice find FBX!

Re: Super SD System 3 Audio Buzzing

Out of curiosity, does the buzzing still occur if both the DAC output and analog PCE audio are disconnected? Has this test been performed to your knowlege? If the buzzing is still there in this case it would seem to imply that the noise is in the 5V rail, which is what I'm seeing seems to suggest. ...

Re: Super SD System 3 Audio Buzzing

Yeah, the noise isn't in the audio coming out of the DAC.
