Edit: I forgot to mention i have retropie install on a ubuntu 18.04 m. I have the bios file (SCPH5501.BIN) is in the Retropie/Bios folder. I get 'firmware is missing: scph5501.bin'. For use with active pre amps to gain full benefit. I dont understand what i am doing wrong here. Power supply recapped and adjusted, sound is said to be on par with reference players. SCPH-101 (Slim) Plus, PS1 games won't work with component and i don't like playing PS1 games on PS2 or PS3. Laser transport disassembled, cleaned, lubricated and damped to reduce parasitic resonances.Ĥ. What PS1 model should i go after and leave out the SCPH-1001 SCPH-5501. RCA connectors added (chassis modified and cut).ģ. Modified output stage - DAC direct output using nos ROE GOLD capacitors and metal film resistors.Ģ. A separate output stage was added leaving all existing electronics intact, the signal is "stolen" directly from DAC output without removing any electronic components so it still functions as a normal "Playstation".ġ. I modified the power supply, laser pickup, and the chassis. The modifications performed on this player makes it a truly excellent sounding piece of equipment.

5501 uses a better laser pickup assembly, it is auto-biasing for proper tracking (important for reading CDR) and positioned further from power supply to avoid interference and heat. Model SCPH-5501 uses the same Asahi Kasei AK4309AVM DAC as Model SCPH-1001 which gives this player a superb audio quality with lots of detail, dynamics and resolution. Modifications to this player yield excellent sonic results.

Sony did a great job putting in excellent DAC in its early Playstation models. I purchased this player from him and did not realize an active preamp was needed to get best results. This player was modified by audiogon member djdonis, who has produced many of these with excellent feedback.
