Playstation as CD-player

[Ziggy]

Found the reason for the problem last night.

The input side of the transformer has a D.C. resistance of only 25 ohms. The DAC will see this as a short circuit to ground, hence the need for a capacitor.

Secondly, as a high pass filter is created, the 20uf caps I have been using are way TOO BIG. They will be substituted tonight for a 1.0uf or less.

are the PS1's still classed as good quality? in todays market, are they alot better than PS3 xbox etc?

[Ziggy]

They are Russian 4,7uf K75-10 PIO caps, same as mine. I have also made one using Soniqs 3,3uf caps. I don´t remember the actual model, but they were those cheaper blue ones. My current prototype ps1 mod has red Wima 1,5uf caps, but they are not good. Audyn Caps work good as well.

ATD-
can you tell us more about you enclosure?
Thanks

I actually asked this before, but I still don't know. I actually bought a new ps1, but have the same problems, it won't play any cd-r's. I did all the adjustments, but it's just not helping. So I think I need to buy a new laser. I bought one already from richpsxparts, and it as faulty. I emailed them several times, and got no response, so...Can anyone recommend a place to buy a replacement laser assembly other then richspsxparts? Also, what would be the best replacement laser for for the scph-1001(ACM, ADM, BAM, AEM)?

I was considering ordering from http://cnn.cn/shop/sony-playstation-c-259_512.html but I don't know which one to order. Will the BAM work with the 1001? I just want to be able to play my cd-r's! lol

Thank you
Joe

Hi

The main enclosure is made of dark 8mm polyvinyl chloride and the top plate is 2mm polycarbonate. The Faceplate is 20mm American Wallnut. It was kinda experimental work and the better one is coming hopefully before summer.

If there is something else you want to know, please don´t hesitate to ask.

I bought a "truckload" of KSM-440BAM units from cnn.cn some weeks ago. Very quick delivery. I have not used any of them yet, but I am 99% sure that you will have to replace the top cover of the BAM unit with the one on your defective drive to make the BAM unit fit in the PS1 chassis. There is a German site that describes this in detail: www. playfidelity.com.

Have just replaced my previous cheaper output coupling transformers with some Hammond 124D's.

Much better tonal balance and improvement in all areas - highly recommend this method of upping the output of the player

Forgot to mention that the link refers to a much more expensive product but the principle is still the same

Does this mean that your PS1 now has an output impedance of approx. 16K?!
