    Started working on this today with my 3-3 (which has the same audio layout as the 3-4). I found 1000pF 100V X7R caps that allowed me to avoid carving into the ground plane. This makes for 100% reversible mod work:



    Let me know if this looks kosher. The tan colored caps are 0.1uF 50V X7R.

    Edit: Fired it up and ran some audio tests. Buzzing and hiss are completely removed! Sound is crystal clear and clean now. Joy!

    Thanks! I went ahead and added "Big Bertha" on the top of 2066D:



    And here's a sample audio recording after the job was done:

    Just wanted to post a new link to an even better audio track I recorded (this time from Art of Fighting). I had forgotten I had stashed in my closet a top-of-the-line Sony analog-to-digital converter deck (it also has a now obsolete minidisc drive) I bought several years ago. It's quite simply the cleanest ADC I've ever heard, so I got the idea to hook the AES3-3 into it and rip a test track. The recording sounds so clean you'd swear it was digital! Here's a link to it:
