Hello fellow members 
It's been a while since my last visit... but none the less, I've kept my self busy with the several project I have.
I was wondering if anyone here could help me out, I'm repairing one of my vintage CD Players (Pioneer P-D1) and would like to know the manufacturer and part number for the optical block...
Thanks in advance and I hope everyone is well.
Stay safe!

"...one of..." your "...PD-1'S..." ������
How many have you got?
I worked on the Toshiba version (many years ago) and have a fondness for Pioneer kit. Therefore I have always wanted one of these, Pioneer's first CD player.
Although not their own, it's a piece of history for me.
They go for silly money whenever they come up on eBay.
Best wishes,

P.S. The info was obtained here in the "DAC List".......

... I believe I have four at the moment 
I no longer shop on that auction site... prices have gone through
the roof
... I mean, just the other day I found a vintage PioneerCar Stereo (KPX-9000) new old stock, and the guy had the nerve
to as $650 for it...
Not long ago, well maybe 2017... I purchasedthe exact same article for $250 and even then I said to myself, man
that's steep for a 43 year old piece of electronics
Oh and thanks for the link
Cheers,

Hello. I refer to the optic and lens that are inside the pickup. You have to open the pickup and remove the grey plastic lid, and clean the optics. You can remove the optic with the coils and clean the hiden parts. Don't move the laser diode for to avoid any disajustment.
Here you can see a KSC-100a that is similar to a OPH-31 inside
CDP-701ES?1??
And this one
L-03DP ??????? ???
I clean it with liquid and cloth for goggles.

Howdy,
First off I hope are doing well and healthy.
I have been keeping myself busy during these hard times...
just wanted to say that I finally came around to connecting
one of my several Pioneer P-D1's to my oscilloscope and follow
the steps in the service manual, regarding "adjustments"...
I can't believe it, I finally have (one) of my PD-1's working!
The thing I noticed, after prolonged testing (playing several CD's)
is that the player starts skipping after reaching track number 15
Anyway that's all I have for now. A big thank you to all that contributed to this thread.

Always after Track 15?
What if the CD has 15 Tracks all of 1 second long?
Or what if the 15 Tracks were 3 minutes long?
These would be in completely different places on the CD. And this would be a very strange fault if it only skipped on Track 15.
Do you actually mean towards the end of the CD?
I suspect you do.
The RED Book states that CD's should be 74 minutes and no longer and your Player is definitley not meant to play any Disc longer than that (because it's not a CD).
Check the Laser can travel up and down the CD easily with no sticking. It could be that the grease on any 'runners' and/or Gears may have become hard and could be causing the Laser to stall, causing the skipping.

Hello,
I'm sorry, I explained myself poorly, you're absolutely right. What I meant to say, is that any CD placed in the player, will play normally (initially while the equipment is cool).
After a while of prolonged listening, the player begins to "skip", making weird noises (through the speakers) and shuts down.
At some point, the unit was serviced, having received a new laser, among other things. It is my belief, that work may have been done poorly. I would like to proceed with a complete adjustment/alignment of all mechanical parts just to be safe.
Once again, I apologize for my poor explanation.
Thank you very much and stay safe!
Cheers
Rod.
