Modifications and repairs on a Sony Playstation SCPH1002

by Mick Feuerbacher, 2005 - 2007


You may have heard that the Sony Playstation is a remarkably good CD player. Indeed this is the case for the very first model, the playstation 1 model SCPH 1002 (or, more general, SCPH 100x, where x = 0 for Asia, 1 for USA and 2 for Europe; differences are only in the PSU, accounting for the different voltages in those areas).
On this page I will, one by one, add a series of articles describing the most important modifications and repairs. These modifications turn the PS into a truly audiophile piece of equipment, which, concerning the sound quality, clearly beats commercial "high-end" CD players up to price ranges of several thousand Euros.
