The dust cover looks great in this picture. However, it actually has a number of bad scratches and I will have to return to fix it some time in the future.  I haven't yet attempted to restore these dust covers so I don't want to practice on this one.  I have a 4004 dust cover that is broken I can use as a practice piece. For now, I am going to start using this Beogram and see if any re-adjustments need to be made.  I should have a replacement lamp for the strobe in about a week so I'll have to open the turntable back up to install that.

This might be sacrilege but I decided to start my Beogram 4000's service out in a mixed system. I paired it with a Yamaha C-80 preamp, MX-1000 power amp and a pair of NS-1000 monitors. The sound with the Beogram spinning a new copy of Tom Petty is excellent. Eventually I may move the Beogram to a system with a Beomaster 4400, an 1970's era Beocord 5000 and a pair of MS-100 speakers but for now I like it with this system.

Here is a closer picture of the Beogram 4000 doing what it does best. When it comes to turntables, I have been biased towards Bang & Olufsen tangential tracking turntables since I first saw a Beogram 4002 in 1976. I had no idea that there was a Beogram 4000 in 1972. It is quite amazing to see and work with this fantastic designed machine. Thank you Mister Jensen.

Awesome job!! I am very happy that this came out so well in the end!

BTW: In 1972 I had a vintage Grundig mono reel-to-reel from my dad...I did not know B&O existed!...;-)

Thanks Rudy! I am quite happy with it too. I was starting college in 1972 and my turntable was a big Elac Miracord 50H. It was a nice, rugged turntable with a good motor. However, once I discovered the Beogram 4002, I had to make the change. In the last couple years I picked up a couple of Elac decks (50H and 770H) for nostalgia purposes.  I was thinking I would play them occasionally but I find myself just focusing on vintage Beograms now.

With everything I learned on the Beogram 4000, I am going to re-visit the Beogram 4002, Type 5503 that I started this thread with and fine tune some of the adjustments. The 4002 is also in need of a dust cover make-over.

I think this thread should provide a lot of good information to those out there that are looking into what is involved in a 400x restoration. I will also post more Beogram 400x information as I keep my working decks maintained and as I repair new ones. My next B&O turntable project looks to be a Beogram 8000 so that will be a new thread.

You both did amazing jobs, Rudy and John. As you say in the US of A, kudos! 🙂

I received a wonderful shipment from Frede today. A Beogram 4000 strobe assembly.
Many thanks Frede!

I must be doing something wrong and I've been looking at the problem for so long I just can't see it.
With the new strobe assembly connected to the strobe control wires, I measure the expected, 120 V, 60 Hz AC voltage when the turntable "On" button is pressed but there is no light from the strobe lamp. Same as my other two lamps I have tried.

When the "Off" button is pressed and the tonearm assembly returns to rest, the voltage across the strobe wires drops to a near zero AC voltage as expected. To me, everything looks like it is working correctly but I still don't get any illumination of the strobe lamp. It isn't necessary to operate and use the Beogram but I still want to get it functioning. Before I give up and go with an LED solution, does anyone have any suggestions of what to try? 

On mine, it takes sometimes more than 30 sec before it lights up. The 1st strobe I had was not working: i was measuring continuity between both ends of the strobe (really weird, as both metal plate inside the glass didnt seem to touch at all) do you measure infinite resistance between both ends of the disconnected lamp?

(Congrats on your impressive work by the way..)
