Addendum to original CDP-397 repair: it wasn’t so easy, like almost all repairs. That’s why this, as a job, sucks.

The CD returned two weeks later with even weirder/crazy behavior. When it was able to play a disc I noticed some audio artifacts similar to bad reading or massive jitter. Touching the front board close to IC302 seemed to improve or fix the problem. Upon closer inspection I saw that IC291 had many broken solder joints, because of repeated heating/cooling effect over years of use. It has some sense, because replaced caps were related to this regulator, and working close to that IC worsened solder joints state.
