Well, I took the plunge and recapped most of the power supply board of my PSX (SCPH-1001). The only one I didn't replace was a big 200V one right after the diode bridge, because Mouser didn't have a low-ESR version. All the other electrolytics were replaced with 105-degree low-ESR Nichicons, and the 4 shrimpy little diodes in the bridge right after the AC input were replaced with UF4007's.
I'm pretty sure that I hear an improvement in sound quality. Voices jump out of the speaker, making a much clearer image. Bass is extended and clear, and highs are a bit less grainy. I'm trying to rationalize the improvement that I hear with the physics of better caps before and after voltage regulators, hopefully it's not all the solder fumes :smoke:
I still haven't gone in there and replaced the horrible 10uF 16V SMD electrolytic coupling caps after the DAC, as Feuerbacher does on his website, http://dogbreath.de .
In short, I highly recommend to people who own the PSX to try recapping with good capacitors, and see if they also perceive an improvement

even though black gates are only 85 degrees C, it shouldn't matter because nothing in the PSX gets very hot... good luck, and tell us how it sounds p.s. i can post pictures of my very untidy job recapping, as the 2200uF 10V capacitor was too tall... I also bypassed that capacitor with a little .0047uF 400V Orange Drop, and I bypassed the un-replaced 150uF 200V cap with a .22uF 630V generic metal film.
