Quick question.
I just bought a BeoGram 6000 Quad. The dustcover says BeoGram 6000, it has the CH4-lamp and the Quad-switch on the right side and quad is working.
But it says BeoGram 4002 on the back, where the red circle is, instead of BeoGram 6000, like it should on the pictures i can find online.
Is this because it is a variant of the 4002 and they reused the cabinet or did i buy a pig in a poke?
Kind Regards,

What does it say on the serialnumber label inside, near the transformer?And on the operating panel?

Here's some pictures of the actual BeoGram.
5501 is a 4002 type number - the 6000 would be a 5502. However 4002s could be supplied with the CD4 electronics and were otherwise identical. I suppose either this left the factory like this or someone had a 6000 and cannibalised it along with a 4002 - would seem quite a lot of work to go to - though I did turn a 6000 into a 4001!

Ok, thats definitetly not as it should be. Probably in the past somebody swap the parts and created "Frankenstein- Beogram6000"...
But basically the BG6000 is the same device as 4002 with CD4 PCB build in from factory as only diference. So if it works well, no reason to worry...

I agree.It's a Frankengram.This was originally a Beogram 4002, and at some point it had the dustcover and operating panel from a Beogram 6000 fitted.
But what about the internal RIAA and the switch on the side?
It seems like an awful lot of work. The hole for the CD4 switch doesn't look handmade at all.
The only difference i can find from a 'real' BG6000 is the text on the back and inside.
Could it be an early release?
The hole for the CD4 switch is found on most Beogram 4002s.Some holes are covered with a black paper-label.Others have the switch fitted to fill the hole - but nothing connected to it.Others again have the quad decoder and everything else needed to play 4CD.The latter ones are identical to Beogram 6000 - apart from the lettering on the Beogram.

I see. Thank you for the clarification. Well, at least it was cheap!
Yes, perhaps a bit odd, but It doesn't make it a bad performer.
It will surely sound identical as the only difference between a CD4 fitted 5501 and the 5502 was the lid and writing on the panel. Unfortunately you will find that the real limiting factor is finding records that have not been wrecked by playing on a normal record player with a cartridge tracking at a heavier weight. Had quite a few and gave up after a while and rehomed the Beomaster 6000. I preferred stereo and B&O made better amplifiers than the 6000. Not sure they made anything quite as beautiful for its time though!
Well thank you for your answers.
Will this be categorized as a BeoGram 6000 or a 4002? I am quite a beolover (unfortunately) and i would love to have a "real" BeoGram 6000 and not a modified 4002.
The serialnumber label counts.
Replacing the dustcover doesnt make it a 6000
I imagine that this was an expedient move by a Dealer back in the day?He probably needed to meet an order for a '6000 but couldn't get one for some reason,so he ordered the '6000 parts needed to convert an in stock '4002,and closed his order.
It seems to be in super condition,and the work has been done properly too,so what's not to like?
Enjoy!

Well, I thought I was the only one with one of these,as I also own a Beogram 4002 that appears to be a Beogram 6000 and has all the relevant 4 channel circuitry and buttons fitted!
The explanation for mine is that it came from Tim Jarman, who found himself with a Beogram 4002 and a Beogram 6000, both of which were individually beyond saving, and so made one good deck out of the two.
Given that it's effectivley halfway between the two, I tend to think of it as a Beogram 5001...
It's interesting that some Beogram 4002s were fitted with quad circuitry to effectively become Beogram 6000s. Was this ever done with the Beogram 4000? Is this even possible?

I am sure it was never done with BG4000. The Beogram 4002 was the successor of the BG4000 and at some (early) point of the development the BG4002 got the place for the quad PCB with the CD4 switch on the right side of the housing.
So to answer the Christians question: There is actually no "real" BeoGram 6000, they are all modified 4002s with fitted CD4 PCB, and matching lettering on the dust cover and on the labels

I have both of them, one 6000 and one 4002. They are almost identical. Sure, the CD4 PCB is missing in the 4002. I liked the idea of having an onboard RIAA-stage but i am not sure it is a very good one. Started to look for a 4002 and found one. Would like to fit a modern RIAA-stage inside it.

I remember that member beolover built a prototype onboard RIAA preamplifier for a Beogram 4002 project. You can contact him and see if he has that available.
Yes, I know that and I have had some conversations with him. The one that he have is made for the later 4002 (type 5513), not for the type 5501 or 6000 type 5502. It will need to be modified to fit. Not sure about its sonic performance, probably on par with the RIAA that sits inside my Beogram 6500. That one is not that bad, better than my 5500 with a Pro-Ject Phono Box. Still better is my Sentec PP-9. Anyway, my plan is to send the 4002 to Beolover for an overhaul, like his insight in motor checkup. My 6000 is cosmeticly not as good as my 4002. The built-in CD4/RIAA is of Little use as I have no intentions to play any 4-channel records.
I can vouch for the motor rebuilds (both AC and DC platter motor types). He has done several for me and the twenty-four hour burn-in test shows the improvement in stability.
