This may be a weird question to ask here, since I assume we all are fans. However I got this Beogram 1000 recently. I have always wanted to try how these TT sound - the cool looking design items.
So this table is in rather good shape. I was able to clean and lube the mechanics well and the idler and silicone belt are alive still. This is not my first TT I am fixing, so I know all the all the right procedures. Now it runs well, silent and holds the speed nicely. Platter turns free for about 30 seconds(witout the belt installed), so the bearing is in good shape cleaned and with new oil.
The tonearm has some rust at the base, so one of the fixing(VTA) screws is not going to come off. I tried the massage this for a week - it will not budge. Before I going to drill this out I need some advise about the arm though. For me it looks crocked/tilted. I do not know how it supposed to be originally.
If the arm has suffered some damage I may want to use some other arm that likes 210mm spindle to pivot and 17,1mm overhang. Like Prichard ADC40 wooden arm.
But there is a question: how good is the table anyway - without the original arm - is it worth the effort to get the working machine out of it. Or the tonearm is the main reason to have it.
The Beogram 1000 was of its time - it has much less isolation from external stimuli than the later decks and the motor will tend to run slow unless serviced. From a value point of view, despite some asking prices on eBay, these are sub £100 decks including cartridge. I have had a couple in my time. They do have an interesting party piece in that they will play when practically vertical - though not a good idea as the bearing will not like it!

Yes, the arm is damaged. I put it on and the geometry is badly off.
So I may want to get rid of this TT however it has some visual appeal to consider.
Which geometry? How do you measure it?
And can you show us the damage, you are talking about?

There is a picture looking at the rear of the bearing counterweight off in my first post. When cart is on the bottom flat of it is tilted/twisted towards the spindle so the stylus runs tilted as well. I can not undo one of the VTA screws to correct the arm leaning back too much.
I see nothing wrong in that photo.Can you show us a photo of the cartridge "twist"?
Interesting. So the pivots in bearing are not supposed to be horizontal and vertical compared to the mounting post? You see, I haven't seen this Beogram before, so I don't know if it is right or wrong.

Collecting Vintage B&O is not a hobby, its a lifestyle.
Well, that's relief. I put the pictures on the top of another and the angles are identical. Ouff! nothing wrong with the bearing!
I got this sorted as well. Now when I knew that the bearing is OK I just twisted/rotated the arm-tube. It appeared that the tiny fixing screw at the bearing was loose and whole tube rotated a bit. I have drilled out the VTA screw as well and re-treaded. I am going to machine the mounting collar clean from rust(and chrome plating as well) and paint it.
I hope it will sound decent at least.
erikik: I hope it will sound decent at least.
I got it together and playing. So far it is no more than decent. Comparing to my fine tuned Lenco L78SE with Shure M91EX.
I need some advise with adjusting VTA. If I rise the base up to have tonearm parallel with the platter the lift lever can not reach the arm at all - ther is a gap of 5mm. The reach of the lift is not adjustable as far I can tell. So I wonder if the arm is supposed to be slanting towards the base by the design.
So I would appreciate a picture of the arm position when stylus is on the record. I looked on the net, but I could not get assured answer.
Maybe somewhat boring sound is due to not accurate arm setup.
BTW Peter, greetings to StPaul - it was my home town for almost 10 years.
There is a manual onsite for silver and gold members, which pickup are you using ?
Great! Thanks!
I have SP6-7.
Something is not right with this arm. When I follow the instructions I get the situation where the cart rides so much nouse up that the back hits the record surface. Moreover the stylus has a downward bend(I think it is made this way but I have nothing to check with) but it is not enough. Without this bend stylus tip would not touch the record at all.
I doubt that the arm is bent out of shape though.

Will this help ?
Is the TA lift correctly assembled ?
Stupid question: does the tonearm have the calibrated spring?

So I got it now. Since the arm is angled two ways you need to position it right. The tube retaining crew at the base was loose so I did not know the right position there. But the screw that holds the cartridge mount in place has 3mm slot for rotation on its axis. Now when I twist the tube so that the angle towards the platter increases(counter clock wise) it tilts the cart to the left - the bottom of it is not parallel to the record(see previous picture). However the hight from the platter is OK. Now I loosen the cart mount screw and turn the cartridge along with the mount(clock wise) parallel to the record and all is well.
And it sounds pretty nice indeed!!!!!
Thank you all. I hope this will help future adventurers.
The picture once again:
Eri:And it sounds pretty nice indeed!!!!!
Now you need a BM 1000, and a pair of speakers from that period, to hear how it is supposed to sound
Don't tempt me! You have no idea how much stuff I possess. I hope not to go down on B&O line any further. I like my Dual CV60 with various vintage speakers including B&O S35. I have a very good phono preamp although Dual has a decent one as well.
