I see that they sell complete cases with cutouts for displays and switches. Do you know if there is a complete "kit"? All the associated electronics that need to be added to a basic transport mechanism is beyond my capabilities. I could probably figure out some nice low noise linear PS with a little help but all the digital controls and readouts is going to be a problem.
Maybe there is a good build thread some where?
Thanks

Dont buy the complete chassis, you will need to find the specific electronics to work with that chassis which is not easy to find and the philips board will never fit in those chinese chassis. Easiest thing to do is buy a complete working CDM4 philips player with a remote control. Make a chassis that will fit the philips main board. Mount the laser mech to the top plate and extend the IR diode to the front of the chassis and you can control everything via remote. If you really need the lcd display you will have to cut a window in your chassis for it.

pioneer dv-300 which is used by goldmund, look at lampizator post

goldmundizator

I have got pioneer dv-355 for $40 last month and it's stock spdif coaxial is much better than my modded qls qa-550.

now i'm still waiting for dv-300 if i'm lucky enough and copy lampizator mod, because dv-355 has different chip and not possible to trace

If you want the exact pioneer that goldmund used it is the DV-588A, it has additional regulators not found on dv-300

I have the DV-588A, its nothing special. These dvd based players never sound good to my ears

Pioneer PDS06 & alike (strong stability= less correction error circuity = less jitter)
Old Philips as well as said above.

If you mean jitter on the bit-flow signal to be digital-to-analog converted, you are wrong. There is a buffer (memory) which every red word from the disc is written to before it is fed the D/A chip and the buffer is big enough to fit a number of samples. Jitter is a timing error in the D/A process that is of a fraction of the sample speed and is easily eaten by the buffer. It is caused by an inferior clock/oscillator. This is just an old misconception. Maybe a confusion with "jitter" in the laser/pit/disc reading process which has nothing to do with D/A conversion precision - these 2 are vastly different and shall not be mixed up.
