GREAT THREAD !!!!
I was lucky to buy a few interesting pcdps: d-465 (great player for the money+my first one, sold rpx-33, wooaudio 6se, electrocompaniet ecd-1 and sony 5400es sacd after listening to this little guy using HD600 and denon d5000 directly from headphone output, never again expensive audio), d-99 (got it yesterday - listening to it right now, great old school sound - I could compare it to my beloved arcam alpha 9 dcs ring dac, pure analog and thick sound, with great bass definition and imaging), d-250(d-25), d-50 mark II - both in like new condition (was really lucky to hunt them down), two aiwas - xp-7 and xp-33, can't wait for them (I have already bought them, waiting for the shipping).
This is really amazing these pcdps have pcm55 or pcm66 inside + headphone amps with symmetric power supplying (I guess the best is still yet to come - d-25/d-50mkII or aiwas).
I am going to use it for a long time so repair threads are really helpful ! I hope we can exchange any informations about these amazing little machines in here (dacs, caps, spindle motors, some repair tutorials etc).
I have a question, my d-99 works great. I have a cosmetic issue only - potentiometer seems to crack from MIN to 3 position (from 3 to MAX no problem), is it hard to clean/lube potentiometer in this model or any chance to buy new and replace it totally ? I haven't opened this unit so far, I am an electronic designer so some PCB working is not a problem ...
These pcdps are really worth some work - they play like there was a soul and heart of music inside, I am simply stunned.
Have you tried better external power supply ? Is this voltage extra processed on the main board by DC-DC switching or by linear regulators or maybe both ? Need to find service manuals and see some schematics.
Some photos of interiors with some comment would be much appreciated !
