Default Lens read once and sometimes not !

I try to set up my ps1 1002 with the voltage knob because I had some drops .
Now it works fine but when I play a 2nd Cd the ps 1 mostly can't read it .
I can see the Cd runs too fast and the lens does noit recognize the CD .

Anyone can help ? Is this the lens or the power supply ? I am not technical ,

voltage knob is the trimmer !

see :

You find the measuring point for setting the laser intensity on the flat cable (arrow). Just below this piont you find the corresponding trimmer

There is lots of discussion concerning this issue. You should read the corresponding postings some ten pages back.

The values working fine for me are found on my website (www button).

Hi,
I thought I would go against the grain and say my PS of choice is the 5552, just remove two 10uf caps and wire direct to the pads joined to pins 15 and 16 (you will of course need to fit your own rca's).
It sounds the same (to me), as the 1002 but has more room inside the case for your Caps of choice,(You can fit fairly big poly's in the lid).

The ones in the picture are only 1.5uf but I have also used 4.7uf in previous trials. The 1.5uf caps are used with 100k grounding resistors to give me what I think is the best bass.

I have also fitted the controller inside (well it's guts), to give on-board control of, play/pause..stop..skip and previous via two toggle switches. The red led came with the cheap controller and I have since changed it to blue, (looks better if nothing else).

I am really enjoying this new cheap hobby, (the 5552's are only costing a few quid each).

Thanks to anyone for pointing me in the right direction, Barry..

Nice! and the caps were probably twice what you paid for the PS1!
So you jumped out from the DAC as per Mick's mod but straight to the RCA's?
How about combining the two? your T and the PS1?
I've already had a go and it fit's in the case!! I'm even looking at a common power supply.......
By the way...nice wallpaper!

Nice! I like the paint job- much better than the stock grey. Any chance of some details on the little platform that it's sitting on?

Hello I just recently got my PS1 and it plays not too badly.

I adjusted the voltages exept I can't catch the 11.7 mv as my meter is too slow. I will check it with a CD playing.

One thing I noticed: the different CD I used now to play some are slightly warped.

Would a good mod be to be ablet to clamp the CD? The CD players have a hub device which grabs the CD between 2 large diameter hubs.

The PS1 has just a clip much like the album CD holders. It may be that the laser mechanism may be able to accomodate thesee small variations.

Any comments?
