Does anyone know the exact PN of the phones vol ctl pot? Either that or a drop-in.
All I know it is a dual log pot 10K. It is bad, and it doesn't seem I can easily deliver Fader lube inside, plus with dead zones I am not even sure it will work. Scratchy as heck.
The last and the least important touch on a unit I have just restored.
But if at all possible, would like to fix that one also.

Yep. Ptetty useless.
Did that. None found.
One somewhat close is a Vishay P9A series. But not 100%.
Thank you, I know that, it is in the manual.
It is an internal company PN. Pretty much their stock number. Has very little to do with the real thing.
It is not a real number, none of them are.
And...I found it mentioned in UED catalog...as no longer available.
The parts in the sch are rarely marked with the real PN. For instance, the Zener thet shorted out was simply marked as 2V4, that is 2.4V one. Plus the internal number.
If you could somehow translate it for me....

20+ year old machine. No original, unique to this unit, parts will be available any more.
The part number kindly supplied by the above poster WILL be the part number for the Headphone Vol Pot.
It will almost certainly have been made for Philips for this (and maybe one or two other units) for Philips by a Variable Resistor Manufacturer (ALPS?) and they may have given it their own part number but only they and maybe Philips will have ever used this.
I VERY much doubt it will have been an 'off the shelf' part that Philips used. It may have similarities to one produced by (ALPS?) but there will have been subtle differences so you had to use the Philips part in the Philips machine (?).
You won't get one exactly like it now.
My advice, look for another CD880 and canibalise it for parts.

CD880 still pretty expensive. Go for a cheaper model to do the cannibalism like CD650 or others. The pot is surely the same 🙂
CD650 from 1986, much older, almost certainly wouldn't be the same Pot.
IF they used it in any other machines it would be from the same 'range' maybe.
Other Players from 1999 may have the same Pot in it but not necessarily so as the 880 was near, if not the flagship player.
Worth getting another, if this is it be your main Player so as to be able to keep it going.
Persival,
I think it is Alps (though I put it back and no longer want to pull it out again to confirm it, as it involves removing the front panel and the tray to access that screw), as I vaguely remember this written on the pot.
Several mfrs are making pots with same exact pot box, including Bourns and Vishay, and Alpha.
The pins' land pattern is the same too. The sole difference is the bushing/shaft assembly. The shaft should be 9mm long D-type and 3.5mm in diameter (3.3-3.4mm).
The only one I found that is very close is Vishay P/N P9A2X000DFRX1103ML. It is stock in Mouser ($20 apiece) and nowhere else. Ideally it would be DFF instead of DFR (D shaft instead of round) but I can grind it down. It is, in a way, even better as the D can have 4 differen orientations (TT Electronics also offers a similar pot with this option but they stack boxes so the distance between the rows is 5mm instead if 2.5mm) and I could put the D exactly the way I need it.
This said, as an EE in R&D, I deal with old part all the time. Sometimes parts get obsoleted by the mfr, and it could be a single source part.
This happens more often then not. Just recently Molex did that to one of it FireWire connectors, so we had to redesign the board as no one else made it.
Marathon just obsoleted the only barrier strip of its kind, so no one else's fits (it is the smallest one out there).
Fairchild obsoleted one of their optocouplers in a particular package, leaving many a manufacturer high and dry.
But part being old means nothing.
You can still buy the oldest TTL/CMOS logic chips of all the old lavors of the 74 logic series which is 56 years old now. You could still buy every popular 1970s OpAmp or comparator. You could even buy old 8-bit processors. Not from brokers, mind you - from decent catalogues.
And.....the Head Phones volume is such a low priority (I don't even own a pair) that it is just to get to 100% from 99.9%, not very important. Just to close the chapter. So for this to buy a whole CD to get one pot, which is not even guaranteed to be good....isn't that a bit risky, unnecessary and wasteful at the same time? If I were to buy a CD player of this old classic cohort, I certainly would do it to restore, not to destroy....
OK, I think I found the candidate (the mentioned Vishay).
They do exist!!!
