Finally received another 1387 module, so rebuilt my number two DAC, which was having distortion in one channel. (The number one build, a kit from @hifinet has always worked flawlessly)
The existing 1387 module was being uncooperative to removal, so I decided to salvage the polycarbonate caps and z-foil resistors to start fresh with the new 1387 on a blank board.
I was able to salvage the RCA jacks by breaking the old board out from around the large solder posts. This resulted in only having to unsolder the through-hole plating left attached to the posts.
Both channels are distortion-free on this new build.
