Hi!
I've got my very own CD50!
First problem to solve, the tray won't get out...

Congratz Jacques, its a very good player, Tray problem is probably belt or old grease, if you can hear the motor, if not, the 2 contacts to check.
I play mine a lot, and love it more each day
Collecting Vintage B&O is not a hobby, its a lifestyle.
Congrats with your CD50. Well -then it's nice that you can just watch Søren's 'step-by-step manual' here to solve the problem.
I actually picked up another one not to long ago. It is the CD player I listen to most often. I just like it better than the others I have.
Hi,
Well after lubrication, the tray remains desperately slow. The belt is good.
Then the CD never reaches the motor platter (it won't clamp onto it) so it won't even turn and rejects the CD. Something must be badly adjusted, but I can't find the problem.
The thing was opened before, there are markings on the mechanism gear wheels.
Where should I look?
chartz:Where should I look?
Jacques, Did you strip the tray mechanism down to the last gear wheel, in mine it was just cleaning and lubricating, if the tray closes slow all the way something is wrongly adjusted or placed, Check the 4 plastic pieces which guides the tray, they are different sizes, and placed wrong, they will make the tray gear bar press to hard against the gear wheel. On the front flap (door) the operating arm is attached with a screw, if the screw is too tight adjusted the tray will slow down when closing the flap. But this only affect the tray movement the last bit before closing.
Remember to mark everything before taking it apart.
Søren
Thanks. What about the disc not clamping?
chartz: Thanks. What about the disc not clamping?
This may have to do with the closing slow, and the drawer does not come all the way in, or not fast enough to operate the the lift all the way up.
Before starting fixing anything with the lift and disc holding mechanism, we must have the full movement of the tray.
It won't lift up to the motor spindle if no CD is loaded, it will then just pull the tray in and close the door.Sounds like something is not right with the opto sensing (if you have a CD loaded, that is).

It has been a few years now but I had one that was nothing more than a good cleaning, relube, belt, and gear realignment. Plays perfectly now at the dance studio art space. The gearing can slip out of alignment a bit over time, caused by worn or slipping belt, forcing or assisting the tray open or closed dried grease. also there is a small bottom cam the hold the upper large flywheel in place that can pop loose.
The clamp does go up, but fails to catch the motor spindle. It plays a CD when it is manually clamped with a rubber puck, when the mech is face up!
Okay, silly me (?) it was all down to setting the brass piece over the big wheel. Too high and the disc won't be clamped, too low and the puck will rub on its holder!
This setting is not mentioned in the SM?
The tray problem: some stupid idiot had replaced the belt with one that was muuuch too tight... I guess the guy had started fixing it and then gave up.
but for me!
Anyway, another fine CD50 for... €30! It even looks very nice!

Well the height setting even affected that! Now the sensor works and the puck fails to rise if there's no CD in the tray. Very clever.
Anyway that should also be marked before taking it off!
Now testing for sound... it lives! Datalink also works with my BM5500... SWEET!
Well my friends, that CD50 is indeed a very sweet sounding CD player. Not bad at all for a machine that was based on an Aiwa machine from 1983!

I love mine, play it more nearly every day, I have a bunch of older and newer Philips, some sony but this one is the best by far.
Søren, I have to say thank you for this subject, thanks to which I could get a clear idea of the surgery I was going to do!
One thing however, about the brass locking thingy, how did you know the way to adjust it? Sheer luck or very meticulous observation, like, "I'm going to count the turns and mark the angular position"?

They are all different - depends on the spindle setting which can vary from machine to machine. as Peter often says no 2 were ever built the same. One of the things i like about all of mine is the occaisonal ping and pop or crackle or wow and flutter a bit. Has a definite analog feel to it.
I didnt have to adjust mine, but as far as I remember, there is an adjustment on the lift, I think the locking thingy is fixed as it depend on distance to the Laser.
My own pizza boxes! Pity the BG5005 lid sags
"Two CD players in the stack?" I hear you say. And why not please?
Yes, that's an A77 at right, and a Nak CR-4 below. I am also currently working on Uher Reports!
Nice stack Jacques, the sagging lid you can fix with an aluminum or chromed steel angle 3 x 5 Mm glued (epoxy) to the back edge of the lid.

Nice setup, Jacques. I love to see systems with more pieces than my own, that way I can point my wife to them and say, "See, honey, I don't have nearly the same number of pieces as Jacques (Soren, Mika, Jeff, Evan, John, etc.)"
And then she says, "No, you can't have the Beogram 1000."
Rich: Nice setup, Jacques. I love to see systems with more pieces than my own, that way I can point my wife to them and say, "See, honey, I don't have nearly the same number of pieces as Jacques (Soren, Mika, Jeff, Evan, John, etc.)" And then she says, "No, you can't have the Beogram 1000."
Next time I move my equipment around, I'm going to place everything in one place for a one time pic, I will wait for the BM 4400 to come, the next S75 on the bay will be mine if the price is right.
Rich: And then she says, "No, you can't have the Beogram 1000."
Sell something, or talk her into believing you are willing to do so. Then you can have the Beogram.

Some day she's going to realize I spend far more money on "the software" than "the hardware."
The less you use on hardware, the more you can use on software
BTW where do you by your 45 sleeves ??
jfrancis: I appreciate the wealth of knowledge you all share. John
Thank you John, we help each other, as you just helped me
Lp sleeves at elusive disc and 45 sleeves at sleeve city
EDIT:
Links: Elusive Disc LP inner sleeves
Elusive Disc LP outer sleeves
Sleeve City 45 sleeves
The inner sleeve for 45's I use is the "7 inch Polylined" all the way to the bottom of the linked page. I use the "Ultimate 7" 2.5mil Polypro Outer Record Sleeve" (third entry from the top) as my 45 outer sleeve.
jfrancis:Hello Soren, I know you were asking Rich about where he gets his sleeves, but two sources north of you are Sleevetown.com and Bagsunlimited.com. Sleevetown I just ordered LP outer sleeves from and while postage was more than Bagsunlimited had much lower prices and a nice product. Sleevetown has sever different kinds of both inner and outer sleeves for 7 inch. I am a lurker on the forum because I don't know much technically but love B&O and the comments on the forum are interesting and enlightening. I appreciate the wealth of knowledge you all share. John
Sleevetown and sleeve city are the same joint

Thanks for the links Rich, have the same problem as you do, a lot of 45s without sleeves, of 500 I think I have 100 sleeves, and many of these in very bad condition
It seems that the CD50 has developed a problem.
On some CDs, but not all of them, the first track will not be found, or the track will start playing at 15 seconds, or in the worst case, the CD won't be read at all, ejecting it (best case) or making the player impossible to turn off without pulling the plug.
Other CDs don't seem to pose any problems at all.
The bad motor lubrication syndrome? Can you give me advice on how to do it? How does the motor come apart if it comes to that then?
Thanks.

Make sure you remember how all of the little nylon spacer washers are set. If I remeber correctly a small allen wrench and a couple screews and the whole thing comes apart. Dillen told me to relube with 30 weight oil . The is a small instruction in the manual for setting distances on the disc drum but it is bogus. you will just have to sort through it.
chartz:On some CDs, but not all of them, the first track will not be found, or the track will start playing at 15 seconds,
Although it is quite likely to be a spindle motor problem (the innermost track #1 needs the most rotational speed, and the player might not reach it before giving up), I believe skipping some seconds at the start is a common feature of these silly players. Mine certainly did it, most often if you were returning from the last tracks. I vaguely remember reading about a service bulletin that increased some timeout related to this...

Thanks mates!
Any photos by any chance?
Hi charts,
had a similar problem not playing the first track and sometimes hard to find the others.
Did a radial bias & focus bias offset calibration to 0mV and it ran.

good memory
Worth a try...
Gunther
Thank you Gunther.
Today the player runs fine. I did nothing.
Yesterday morning it all started with a Beatles 2011 CD that my CDX also finds hard to read.
Is it possible that it perturbed the player like that?
I will check on that radial balance setting nonetheless. Hoping not upsetting anything!
By the way, do you consider a CDR burnt at the X1 speed is a "zero default" CD? Or a CD made in 1982 perhaps?
chartz:Today the player runs fine. I did nothing
I have had problems with first seconds on the first track and lately not reading the first CD, but both failures only when coming of standby or disconnected for longer time, after playing one CD the next one starts OK, and it reads all kind of CDs, CD-R, CD-RW, and a pirat copy someone gifted me.
As I have mine open for belt change, I will go look for a 100Kohm resistor and solder it in, will report back with more and pics.
So we have the same problem exactly!
It would be nice if the radial balance setting solved our problem. Let's find out shall we?
I will try with the 100K resistor first, but I only found a 100KR 2W in my stock, and I think it should be a 1/4W so I will have to go and buy one tomorrow.
I do not like to adjust the focus and radial balance, as the laser works and focus OK after playing one CD I don't think that there are problems there.
If the resistor do not solve the problem I will go there.
Just took a look in the manual, to make the focus adjustment a oscilloscope is needed, so its a no go for me, unless its sufficient with a DMM.
