#SCPH 5501 MOD CHIP UPDATE#
Once you find a solution to your issue, even if you don't find it from this community, please update your post or post a comment to let the world know the solution. Arcade posts are absolutely welcome as well. Maybe a Bufflo-III.Anything related to console repairs, mods, hacks, advice, questions, general technical discussions, or games and accessories, is welcome here. Time to try something "superior from ground up". All in all, the final result is more or less a disappointment to me.
#SCPH 5501 MOD CHIP MODS#
with so much mods involved I was expecting the PS-1-extreme would at least beat the X555ES. The X555ES is more involving, the PS-1 images better. However, when comparing to my modded Sony X555ES (opamp, output cap), the extreme-modded PS-1 is only about "as good", not "better". The result: very fine sound, easy to listen to. I did try a few things to the transport mechanism, the difference is not obvious, so I left the transport secitn alone. Maybe it is because I already have pure battery power in Mod-(3) so the linear supply is only powering the digital and transport section. Mod-(1) and (3) gave obvious improvements, mod-(2). When downloading, you should go to Save Link As and change the file extension to ZIP.
#SCPH 5501 MOD CHIP INSTALL#
Here’s a comprehensive guide on what you should do to install SCPH1001.bin on your computer: Download SCPH1001.bin from our website or any other resource. DC blocking is done outside, either by using film caps, or using the uPA (as a pre-amp/volume control).Ģ)external linear-regulated power supply, power is sent into the ps-1 via a 5-pin DIN cable.ģ)5V NiMh battery power pack in the PS-1 case, to power just the DAC chip. PS1 BIOS download is a very easy procedure. I will let the unit run for a few days and listen to it again.Īnyway, the extreme mod on PS-1 has been done.ġ)signals tapped directly at the output pins of the DAC, piped out (raw, with the DC component) via 24awg HGA silver-teflon wires. The 196P VitQ's on the other hand were brand new, so there could very well be a difference between 0 and 2 hours. It might have something to do with capacitor burn-in: the Russian teflon I installed already had about 200 hr on them, so the extra 2 hr should not do anything. The sound got a bit finer and stage got a little wider. The base-line modded unit continued to improve in the next 2 hours (at least that was how I felt). with so much mods involved I was expecting the PS-1-extreme would at least beat the X555ES. The X555ES is more involving, the PS-1 images better. However, when comparing to my modded Sony X555ES (opamp, output cap), the extreme-modded PS-1 is only about 'as good', not 'better'. Then 30 more minutes went by and the muddy-ness of the stock 1001 became more and more annoying, I started to really appreciate the clear-ness the base-line mod brought. The result: very fine sound, easy to listen to. During the first 10 minutes of comparison, my thought was although the base-line modded one has more details and such, the stock 1001 is just pleasant to listen to. The stock PS-1001 has a "rounder", more meaty sound. The base-line mod sounds more detailed, no doubt about it, sharper sound with a slightly wider stage. components in the signal chain: 26awg silver/teflon IC ->modded SRM-1 (SIO output caps, 600V bias) -> recabled ESP950. Impressions (comparing to a stock SPCH-1001): If you have done mods to your PS1 please chip in and tell us what mod works best and what doesn't.

I have already prepared the pins, it was kind of tricky, I actually had to perform the pin lifting and soldering under a 10x microscope (and the magnification helped a lot). Most of the above had been done by various DIY'ers, with the possible exception of an independent pure DC supply for the analog stage. SCPH-5502 - European version of the 5500. SCPH-5501 - North American version of the 5500. but before that can happen it will have to beat my modified X555ES CDP. CD drive mech was relocated, onboard electronics shortened by 20 percent, seperate ports for A/V composite output were replaced by the A/V Multi Out port. *If the result is good enough, I might mount the transport to a thick chopping block and recase the circuitry. *A functional control key pad so it actually looks like a CDP control (actually a re-cased controller). *independent analog power supply route, I will use NiCd battery power for the analog stage of the DAC chip. *external linear power supply for main power. *pipe out audio signal directly from the DAC, and try boutique caps (Auri, VitQ 96P, and FT-3 teflon) in the signal path. I guess using PS1 as a CDP is old news, but I just got mine 1001 and here are the planned mods:
