Hi everybody,

I have spent days and days reading the many posts on this subject. I have also visited Mick F excellent website. I have decided to take out my son's PS1 (it's a 1002 model) today. I have quickly check laser, drill holes on the case over the PSU, connect audio cables from AV output, put it on a pillow and listen to make my own idea. I must say that I'm very impressed by the sound. I will spend more times listening and make comparison with/without pillow as suggested and also with other CD players.
Excellent job guys and thanks a lot for posting all this info, I will be back later after some listening.

Enjoy,

Just a quick question to those of you who have exchanged the power supply: was it possible in your case to run the PS1 when supplying the voltage only via pin 1 to 4, i.e. could you leave pin 5 to 7 open as I described on my website?

I am asking because Dommy told me that he has tried several PS1 and most of them required voltage supply also via pin 5 and 6.

Thanks for the information,
Mick

Mick_F. We had assumed that your PS works with the power supply you made. Do you use power to all the pins ?

I am just about to make one using only pins 1-4.

Sorry, I did not want to cause confusion. Of course my power supply works the way I described it, i.e. with voltage only on pin 1 to 4, with all PS1 I worked on. I also know from a few other people that they built it the way I wrote and it works perfectly. However, I was surprised when Dommy recently told me that some of his PS1 only work when he additionally connects pins 5 to 6 and otherwise do not run at all.

Therefore I am making this little survey. If other people than Dommy made this observation, I will make a corresponding note on my website.

Btw you can easily test it on the stock PS1 by opening the case and removing connections 5 to 7 on one side of the stock PSU connector.

Mick, the first 1002 PS I put my linear psu into only worked around 20% of the time.

Quite often it would hang on the intro screen sound (stuck playing same note over and over again) It would work most of the time if I plugged the 3.6 in after the 7.6V.

In the end I scrapped this PS, and so far its working fine in my newly modded 1002.

It could have been a complete coinicdence to be honest.

Mick_F. My 5552 has only 5 wires running from the SMPS to the main board.

From front to back, Brown, Red, Orange, Yellow, White ?

Do I still use the first 4 only ?

I will try and measure the voltages later,got to take the family out today !

Rob.

Yes, the 5552 has less leads. I guess the 5th is for reset. Just leave it open and try if it still runs.

Default PSU all leads connected

[ If other people than Dommy made this observation, I will make a corresponding note on my website. ]

Hi,
because I had difficulties at startup sometimes , I connected all wires from the mainboard to the DC-PSU. Seems to work more stable now but could be coincidence...see picture.

A question:
With my reccently modiefied PS there is a strange phenomena. I set up bias and gain, adjusted the laser intensity (played around quite a bit) but it will still skip on the first track of a CD. This is a new laser unit though.

Any suggestions?

Mick_F. I have measured pin 1, (7.49v) 3, (3.55) and Pin 5 (using pin 4 as 0) (1.95v)

Should I still set voltage at 7.6 and 3.6 ?

Thanks for your help

Rob.
