Jacques, what is the serial number and series on yours?

John

Beolab 5000 type 5303, serie 08, serial number 46619.

What about yours Christian? What is the type, series and serial number?

The one Søren just restored was a type 5305, series 80, sn88262. One of the latest Beolabs according to Frede. It would be interesting to compare the differences. Is there a way to tell from the numbers what year is was made?

John

5303 no 65500

I see some changed caps in the pic, did you change them Christian or did it come that way

Image was half way through recapp.
I have used my choices of caps. not axiell caps but radiels because thats what I had at home.

The 470 uF have  I increased to 1000 uF as they are pure smoothings.
The only reason they were choosen 470 at the time was limitation of size.

There are a few caps here and there that I have increased value due to  electronic design. 

And have made my decision not to do as deep renovations you did Sören.
my BL5000 is in excellent shape.
I am awaiting some more caps and after that I will slow start it with 30% on the variac and measure idle current. If that goes well it is ready

I am not so sure that transistors needs to be replaced, if they work the work.
IIf I take decision to replace the 6002  I will use equalient BC549 and 559 as they are low noise transistors.
I have checked out the spec and they should go well 

In after thought I would go for radials caps instead of the standing axials easier to get equivalent sizes, as for the black drop TRs Frede recommended me to change them with BC 550/560C but BC549/559 are indeed very close. Frede has found out that these TRs gives intermittent failures (distortion) at times.

Compared to mine yours look very clean, how are the fronts ?

May I ask, on what do you base that statement?

And you are not using WD40 anywhere in a B&O - are you ?

Martin

Yes you may dear Dillen.

It is obvious that it is very tight in the Beloab. 🙂
I cant see  how a 1000 uF would fit inside there.
Even though the stabilizing circuits , dont you think they would have crammed in a 1000 uF if it would be possible ? 🙂

WD 40 ?😁 ohh no, The reason it is on my kitcchen table is that before I got to the BL5000 I was dealing with a tricky mechanical problem inside of a Pioneer turntable from the 70ths  ;)
