Hello everybody,


Well, I've replaced the c2103 capacitor, with the right one (47ùf..) when my cd unit begins to spin, rattle and then stop.

It was nice to play cd again, when another thing happens, the cd start well, the '"number of songs" appears, the first one play, the other one, then the cd stop and switch off the unit !!!!

of course, if someone could help, it will be really appreciated...

thanks

47uF should be fine. It's the filtering charateristics that is important which also makes the circuit ask for a
certain brand/type of capacitor. The original is a blue axial Philips and that's what I would recommend, they work everytime.
Don't expect any other brand/type to function correctly.

Replace the remaining caps on the servo board while you are at it.
It will provide less supply ripple and less signal jitter.

I think it should be 33uF?

Ask Graham (joeyboygolf) , he's the expert on these machinesSmile

33µF was the original value of C2103 but in the old forum Martin (DieBogener) mentioned that he also had success with a blue 47µF.

And i had success with a blue 68µF Capacitor ( Original Philips) which i had when i needed a replacement for the C2103 in my Beogram CD6500.

The capacitor has to be a blue Philips / Vishay with at least 33µF / 16V but it can be replaced with a bigger one 47µF for example as long as it is the 'famous' Philips type. Bigger values often enables the playback of CD-R's.

Ah, I think Graham mentioned that also! Good to know! Very coincidence but this evening I replaced the C2103 on my BC9500 and it runs smoothly! Only the cassette belt needs to be replaced and I ordered 3 to get the other units fixed.

To Leslie, Martin or any Beo Samaritan,

I have similar problems with my Beocenter 9000, type 2501.

The CD player reads fine a few discs as far as I open the lid and before playing them, but refuses to read a large majority of them.

The cassette belts need to be replaced.

The mute relays to the main speakers are certainly dead since the auxiliary outputs are working fine but there is no sound out of the main ones.

Radio works fine :)

A lot of problems, but it is my beloved fisrt Beomaster, bought in 1987 and I want to save it.

In addition, it is the only part of my system to which I can hook my Beogram 6006 (still working except the arm which often stays "stuck" in the upper position... help needed too BTW).

To anyone who has the knowledge and the will to help me, I would be very happy to buy the complete set of capacitors for the CD, belts for the tape player and the mute relays.

Leslie, if you still have the service manual of Beocenter 9000 (type 2501) and Beogram 6006 (type 5625), I'm interested in buying them. Can you make me an offer through PM?

Kind regards to all of you...

... and best wishes for 2013!

Yann.

Does someone have a list of these? (for ordering)

Kits are readily available, slightly different to match the various deck types fitted.
Drop me an email.

Dillen can provide a kit containing the correct caps for the job. I suggest that you make contact with him though this website.

Well, thanks Dillen for the right kit. As I told you, I've changed all the caps of the kit, but something still goes wrong.

When i tested it, the number of song in the upper display was right here, but nothing appears in the down display, where you have the 0 to 9 number, and the index light on...the cd don't seem to start, and after a while, unit switch off again. and now, nothing light on, neither in the upper or down display...

i've changed all the caps of the pcb 31, still nothing...But the crazy thing is that I try the pcb31 with the cd unit on my second 9500 (in poor condition, no k7...) AND this little boy play all the cd I gave him !!!!

do you think a bad ghost or something is in my beloved beocenter.

poor me....

Dear Members, i know, this is and old thread, but as long as it can be found via Google easily, i have to clarify this. 

These axial Philips capacitors are long gone out from production and nothing is the same or even similar with later Vishay/BC branded ones. These Phiilips capacitors are well known for failing in everywhere, especially if some (far from lot!) heat or impulsive loads are present. While japanese old brands still can be usable after all these years, Philips aren't. They were superior caps-till they were knew, but now they are goner. And NOS (new old stock) ones aren't an exception, they are getting deteriorated after such a long storage.

However. There is nothing very special in this position like C2103 to stick with certain manufacturer's certain product. It must have low ESR and high ripple capability to stand out and thus, any well known brand's well suited low ESR series should do the job. What you have to avoid is the el cheapo lesser quality mades and no, general purpose ones won't do the job well, or not do it for long time. I prefer Panasonic FC in this position, but Nichicon PW should be fine just like Nippon or Rubycon low ESR/high ripple series.

And never forget to replace all other Philipses in control PCB, they will surely fail.

What nobody else told here-check especially the regulators solderings (near the heat sink) and resoldering all the ICs are well recommended (avoid extreme heat stress, do it with caution!). These older Philips boards are full of weak or broken solder joints.
