I received a Beogram 4000 with a Beomaster 4000 for Christmas from a very lovely girlfriend! Only problem is I have just set it all up to find that the Amp works fine although the turntable just wont power up.
Does anyone know what could be wrong with it? it was apparently all working before I got it?
Any help would be appreciated.
The BG 4000 has a fuse (or 2 ??) inside, that is the first thing to check, if the fuse is blown, check the transformer primary and secondary lines before putting in a new fuse.
Collecting Vintage B&O is not a hobby, its a lifestyle.
Thanks Soren,
I will check the Fuses tonight and see if any of them are blown.

Great girlfriend ! :-)
Hi Soren,
I finally had a chance to look into the fuse problem with my beogram 4000, I found one of the fuses was blown.
I had a look at the transformer primary and even had a new plug rewired as the old one looked vintage.
The only problem is i need to know what the replacement fuse is? it has T250/250 on it, does that mean i need a 2.5A fuse to replace?
Thanks in advance.
No, 250mA slow
Brengen & Ophalen
Leslie: No, 250mA slow
Depending on where you BG was sold, you have a US or EU type of fuse, bring it with you the shop, to get the right one, and buy at least 2 pieces.
If the fuse blow again, you will have to check for failures, best to start up with a dim bulb tester, that will save fuses.
Thanks :)
It was originally from the UK, I will buy a few of them as spares.
Thanks

Is this the right one?
thanks
Yes Sir
Great, thanks for all your help.
I will order them now and let you know how i go when i receive them and put them in.
If you live in a 110-120V area and moved the Beogram from a 220-240V area, you will have to set the mains voltageon the switch (unpowered) and change the fuse accordingly.If 250mA was correct for use in 110-120V areas, you will need 500mA to stop the fuse(s) from blowing in 220-240V areas.
Remember Ohms law ?

Hi Martin,
The person I purchased the set up from purchased it in England in 1972, he later moved to Australia and brought it over with him.
He said he has used it while he was here so i'm just replacing the fuse that is already in it. I guess if they blow then I will up to the 500.
Hi Guys,
I replaced the fuses but no luck, still no power!
Any idea of the next thing to check? anything you would replace? Transformer? how do i test it?
Thanks.
Did the fuse blow again ?Did you replace the fuse with a correct value or "just a similar" ?
No the fuse didn't blow again.
The fuse cover says '2x0,25A.TRAG'
So the fuse I ordered was this one - Here
Is that the correct one?
Just one question: did you unplug the deck with the carriage to the left?
If so, press STOP to switch it on! Otherwise it will not wake up!
Jacques
I just tried what you suggested and no luck.
There is power getting to the fuses as I stupidly touched them and got an electric shock, this is getting frustrating! I have had this record player since Christmas morning and haven't been able to get it to power up.
Does Anyone have any other ideas as to what the problem might be?
Instead of trying to get yourself killed, first of all read the manual, maybe you dont know to operate the deck. Second if the deck still is giving trouble, start with connecting a dim bulb tester, best, in connection with a variac, if you have current to the fuses and they dont blow, there is failure farther inside the deck, and the dim bulb will show you if it is so, then check the schematics and start looking for failures, not working mechanics or electric components.
If you dont have any knowledge about electronics, leave it to a repair shop, BG are not that complicated and a good audio technician should be able to get it working.
Oops, double post.
I agree.
It would be a bonus for us if you could post nice photos of the various parts of your Beogram!
There is a great fault-finding diagram in the service manual too.
Ok thanks guys,
I will look through the diagram and start trouble shooting. I will get a dim bulb tested and see what that shows.
As far as the pictures I could probably post some on the weekend for you to look over.
Thanks again guys, I will keep you updated.
Hi,
Any new developments then?
Where in Australia are you Beowaff?
Hey guys,
No new developments at the moment, I have been busy with work so I haven't had the time to look into it further!
Andrew im in Melbourne.
I will keep you all updated.
I am based in Melbourne and know someone who can work on these units who knows his way around them pretty well, if you want his details shoot me a message.
Andrew
I just wanted to know if anyone knows someone in Melbourne who can look at an fix my Beogram? Any help would be really appreciated.
Dillen: If you live in a 110-120V area and moved the Beogram from a 220-240V area, you will have to set the mains voltageon the switch (unpowered) and change the fuse accordingly.If 250mA was correct for use in 110-120V areas, you will need 500mA to stop the fuse(s) from blowing in 220-240V areas. Remember Ohms law ? Martin
If a device consumes the same amount of power, then according to Ohm, the current will be reduced be a half, when the voltage doubles.
Roughly (as with AC current it's different) P= U x I
I wouldn't bother with the dim bulb if the fuse remains intact, as we know there is not a demand on current in this case. However have you know checked the other two fuses (one inside a yellow sleeve)? Looking is sometimes not enough so put a meter across both of them.Now, just because you received an electric shock does not mean the neutral wire in the plug / cable is not loose! So you need to check that the transformer is energised. After this, you need to check that the secondary of the transformer is energised with a voltmeter on a.c. volts, or skip that and check there is DC voltage of approximately 24V at the large transistor next to the motor - DO be carefull not to short any wires here!There is also a second 6V supply too which you should check at this point.

Shouldn't it be the other way 'round?
Agent00soul: Shouldn't it be the other way 'round?
Referring to?
Thank you, I will have a look and see how I go.
Finding the time is the key.
Ok so I have had someone look at it and has said that the transformer is going to need to be replaced, thats if i can source one??
Also the tone arm needs realignment and most moving parts need to be lubricated.
So my question is where do I get a Beogram 4000 5215 Power Transformer from, any ideas?
Listen to Martin, I had to ship my Beogram 4000 all the way back to Martin in Denmark only to find out that I have the wrong fuse. My 4000 was delivered in Germany and although reset for 120v no one knew to change the fuse which kept blowing.
