Both AC and DC motor versions of the Beogram 400x turntables are great once the motors have been rebuilt. If the motors are still original then the oil in their bearings have to be about gone by now. I have had Beolover restore both AC and DC motors for me and they perform like new again.

As Jacques said, if you consider yourself a B&O completist then you really should have both types :-). 

I'll skip my turn for owning two BG since I consider myself enough B&O... compulsive...

My intent is to send the motor to Beolover and put the money on the table I want to keep.

If, sound wise, they are both "equivalent", I'll stick to the one I have.

Thanks a lot for your inputs guys, much appreciated as always.

The biggest factor in how it sounds of course is the cartridge so make sure and allocate money for that component.

it has an MMC6000 but I don't know the wear of the stylus though.

I would also mention that the ribs on the platter of the AC version are thinner than the one with the independent subplatter (4002 DC and 4004), making it aesthetically more like the 4000. It might not be a big concern though! However, that detail has always bugged me!

Hi,

That's right. The AC BG 4002’s had a 4000 platter without the painted strobe markings. I never quite understood why B&O used fragile paint as others - the Duals, Technics et al, were using cast markings.

I believe that there are also AC and DC versions of the Beogram 6000. What's the easiest way to tell which version I have? Is it by looking at the ribs on the platter? Could anyone post pictures of the two different versions so I know what I'm looking for?

Hi, 

For your curiosity, here's an old post with a nice pictures showing the subtle difference between the two kind of platters :

/forum/imported-unmapped/beogram-9500-riaa-for-beocenter-9300#post-2264633

The one with the thinner ribs (Beogram 4000, 4002 early and 6000 early) is made in one heavy block. Later types have a black and smaller subplatter, seperated from the main aluminum platter above it.

I don't know, however, if the switch between AC and DC followed exactly this manufacturing difference.

Type number for these models start with 55 followed by two numbers. on the 6000, I think the third number can be "0" or "1". The fourth number, if it follows the 4002 structure, is a market designation (GB, USA).

If the third number is "0" as in type 5502 or 5505, then, the deck is probably the AC version.

The best way to confirm would be to look at the electronics : The AC version has four big capacitors, right above the motor. The DC version as only one.
