B & O Turntable 4000 Series

[poynton]

Hi.

I have acquired one of these.

Can anyone tell me how to dismantle it ?
I can get the turntable off but cannot see how to dismantle further.

The belt is off and it does not appear to have any life.

Any help is appreciated.

Hi Poynton

I also have one of these horrors - a 4002. I've owned it for years and keep it only as a curiosity. Every year around this time, I play the thing. This year (a week ago) I set it up and all the old bugbears returned. When I bought it, it had an interesting extra feature - 4th speed at around 100rpm. I cured that by replacing a cap or two.

Sorry I cannot offer too much help as this is a complex matter. Perhaps some of the clever peeps here will give you some better advice.

Mine is, whatever you do, don't dismantle unles you know what your're going to do and why.

Happy New Year

Hi Andy,

It's been years since I seen one but, if my memory is correct, starting with the platter removed, the outer wood trim slides towards the front about a 1/4 to 3/8 of an inch. Push from the back corners of the wood trim towards the front, (I can't remember if there were two flat head screw in the back corners that held it or if the dust cover had to be removed)

The small aluminum rectangle on the right side needs to be removed first. Once the wood trim is slid forward, the right edge of the panel should lift up out of the slot on the trim assembly that holds it. Once the right edge is up and clear of the trim it will slide to the right unclipping it from the table.

The front edge of the aluminum square around the platter forward should be able to be lifted from the slots in the trim assembly. Pivot the front of it up and slide the panel forward to unclip the back edge.

Definitely remove the cartrige before attempting this. It is slid into the end of the tonearm. You can probably get a look at a cartridge at Vinylengine.com

Hopefully this works, like I said it's been 30 years. I used to service them under warranty.

Let me know what you run into, or if it works.

Regards, Mike.

I have an very old 4002 and a service manual too. the 4002 is a hanger queen and had not worked in 30 years.

I'm beginning to look for a turntable that will help rekindle my love for vinyl. I like the idea of a tangental arm TT, but have read about the horrors of the 4002. Did B&O make a version that was dependable and of higher quality that I should consider?

You might look at the 8002. Seems to be a refined version of the 4002. I haven't seen one though, just examined the schematic.
