If running directly out from the DAC to the phono sockets, and omitting the output capacitor (my pre-amp already has one), does one need to keep the 22k resistors on the phono sockets of the PS, or can those be omitted also?
Many thanks!

Skipping the resistors
Hi John,
you can skip them .. just wire directly. I have a direct wired system as well as a filtered system and there is a small improvement in the direct sound. The resistor is part of the capacitor - resistor filter to stop low frequencies (below about 3 Hz) reaching the amplifier. If you don't need one then you don't need the other.

I had the the original ps1 but managed to knacker up the pcb. They are difficult to find in the UK. Could I buy one over from the states and then simply replace the internal power supply so that it would over here with the 240V supply?? i have a nicely modified Power supply that would do the trick!!
Excellent!
I managed to knacker the PCB when removing a mod chip and since then I cant get the CD to spin. I've done one or two small mods to my PS, the remote control mod will be next.

I have a spare PS1 PCB if you want it? The output leads are already wired in place, plus flying leads for an open/close TOC switch. It's just the PCB - no chassis, PSU etc.

Can you send me a PM with details about postage and how much you want for it!! Thanks in advance m8
For North America, the Playstation 1 models best suited for modification are Model SCPH-1001 and Model SCPH-5501. These both use the AKM 4309 DAC. I don't believe Model SCPH-7001 uses this DAC. It might have a CPU with an integrated DAC.
To modify Model SCPH-5501, you must install RCA jacks on the chassis as this model does not have any RCA jacks in stock form.

Thanks Rich,
the 7001 doesn't have RCAs either. I have a modded 1001 that works (some skipping) and thought I'd ask before tearing into this one. I re-calibrated all the voltages per Dogbreath so I might need a new laser. Any suggestions?

To keep costs down I'm interested in re-capping my SMPS. Its a 240 UK model, the Powerpack version is 1-468-159-11 would these components work on that version of the powerpack or would I have to look for different components so they are to uk 240V. My knowledge of electronics is pretty crap! I'm trying to learn 😛
Hi.
Does anyone have the schematic for 1000/1/2 or 3? I would like to see how the A/V connector is fed and from where regarding the videosignal/s. On the ps2 you could get VGA if you had the linuxkit (which I have) or if you used some games (which I don't have and don't know more abt).

G'day all,
I just stumbled upon this thread after a search, as I've been using a PS3 as a source for a while now.
I see theres 2661 replies to this thread, I think I'll struggle to find the time to read these all. Any chance someone could give me a quick summary of the topic?
I can narrow it down. I'm just about to play a PS3 into a lavry da11. It's just a plane old spdif into the dac right? Are there upgrades you can make to a PS3 to improve audio or are the discussions in this thread along different lines?
Cheers, James

I just picked up two 1002's for the fantastic price of £15. So the plan is to do the full Mike F/dogbreath.de mod to one of them, build a new casing, and add a 3"/4" LCD, and then compare it to the other, and then do something with the second, however, I have never done any circuitry building before in my life, so I have no idea where to get all the parts from (ie caps and resistors, pcb boards). I'm not stupid so i think i can manage this, however is it advised, I start with a few amp kits first?
Also, is the laser part of the reason these are so good, or is it better to replace them; because i was think of replacing it if it isn't, as at a store near where I live, the guy working there says he has many old marantz readers which are meant to be high quality, unfortunatly i cant tell you what they are (i cant remember), but will update you tomorrow, when I go there...
Many thanks in advance!

If it aint broke don't fix it!
The laser unit will either work or it won't. I believe that you can get replacement Sony units from the likes of ebay. However as PS1s are as cheap as chips, if the laser goes, just buy another PS1. The laser sled is different in the 5552 to the 1002.(you can mod a 5552 without the audio outs, you just have to add two phono sockets)
If you are going to do the MickF mods be aware that the pictures on his site are enlarged. In reality the parts to de-solder are minute and can be tricky if you have no de-soldering experience.
Forget the Marantz lasers unless you have a dead Marantz CD player.
