Hi There,

I recently rediscovered my love for vinyls, and I decided to fix up a 4002 that I bought on Craigslist a while ago. I also thought it a good exercise before I tackle the 6000 that is in my queue.

IT turned out that I needed to replace the light bulb in the tracking sensor, and I did that with an LED (inspired by Menahem's great PDF that is posted on the internet). I went a slightly different route and did it with a 3D printed part that holds the LED. I made a video about the procedure. It is posted on my blog at:

http://beolover.blogspot.com/2014/11/beogram-4002-conversion-of-tracking.html

Here a picture of the bulb housing after replacement:

Great how-to Rudy! You do like LEDs, don't you?

Absolutely! LEDs are awesome! I want to see these units in service for another 30 years, so LEDs are clearly a way to go. Here is another one:

I exchanged the light bulb in the detector arm with a LED. Here is the video:

and an impression of the final result (I like the 'back to the future' feel of the white light LED, but of course one could also use an amber type with a more authentic incandescent feel if so desired..;-):

O.k...now I officially ran out of LEDs to replace in this 4002..;-). Here is the Speed Selector Circuit Video.

and an impression from under the hood:

Of course, I also needed to implement some 3D printed parts into this Beogram 4002! May I present?: Stereo lithography printed bushings for the transport locks! Here is the video:

and an impression of the printed parts. While not perfect yet, I really like the resolution of these printers, much better than the Makerbots:

Nice job with those bushings. I suspect that Harry could do well on this forum if he starting a bushing replacement business. Most of the bushings in these machines are most likely deteriorated.

All the parts I design are available to other B&O enthusiasts! Send me an email at beolover@gmail.com.

I will also be happy to provide the STL files to those who have access to printers. I am a bit behind with my website, but I will post the files and additional info in the near future.

And here is yet another 3D printed part for the 4002! The lowly but important cabinet guiding washer!..;-)

I decided to take my Beogram 4002 still a bit further into the future after running out of light bulbs to replace...;-). I designed a plug-in remote control receiver that allows the control of the turntable with an Apple remote. I am so in love with my newly rebuilt keypad that I did not want to use it anymore it to preserve its looks for 'future generations'...;-). The remote also improves the cueing function of the turntable.

Details and a video are posted on my blog.

Hi Guys,

I printed another Beogram part with stereolithography: A MMC cartridge protector. Seems most are lost...So I can finally give my cartridges the protection they deserve..;-). Details are on my blog: http://beolover.blogspot.com/2015/02/bang-olufsen-mmc-cartridge-protector.html

Fantastic to see someone using 3D printing for all of these 'lost' parts. I am on the hunt for some covers for the SP range of cartridges. Got a fair few of them now, but none of which have covers!

Maybe 3D printing would be the answer!

I think that is absolutely doable, but one would need at least one original to take measurements...;-)

Hi Guys,

I designed a plug-and-play part that replaces the tracking sensor light bulb assembly in the Beogram 400x. Comes with an updated video. I was not fully happy with my original approach...too much messing with the Dremel tool for my taste...;-). More details on my blog:

Thanks again Rudy for these wonderful videos. I really enjoy them and this latest documentation of the adjustment procedure is a big help.

My pleasure! My mission is to keep these babies going...;-). Here is another one about relubing/adjusting the tone arm lift mechanism.
