Things are moving right along with the BeoCenter 7000 t1803 that I acquired recently. Martin has the tapedeck belts on the way and I got the tonearm adjusted so that it drops confidently into the start zone, no longer falling off the record half the time.

 

Poking around here, I saw numerous questions about the aluminum door over the control panel but no one asked about the plastic cover over the turntable. The cover on mine opens nicely but won't stay up. Hold it or drop it. I presume I'm not the only person lacking a third hand to hold the thing up while pressing the "turn" button and applying the record cleaner to the disc. Shouldn't the lid stay open?

My investigation has found two wire springs that don't seem to be doing their job. They are to each side of the lid, right and left. Should there be a third spring, in the middle? Checking the service manual, I'm unsure whether there is a hinge piece, similar to what the control panel door has.

Am I the only one with a sagging door?

Second question - I noticed  question from someone who bought a type 1801 which he brought with him to the U.S., and now needs to change transform to operate on 110volt AC. If that can be done, how's this? My type 1803 came with an FM-only radio. Would it be possible to swap my FM only with the AM/FM/LW radio from a type 1801? I would enjoy that. I don't expect that would be possible.

Thanks for your advice.

That spring is horrible! I thought I could just take out out, bend it  and put it back, but it's nearly impossible to replace! I ended up propping the lid up with a chopstick. If you want to be all B&O like, use a fancier, wooden chopstick instead of bamboo.

Does your Beocenter have a voltage setting switch at the bottom?

To Martin's reply - My t1803 has no voltage switch. It took me only a few minutes to realize why you ask. The 1801 operates on different voltage, which means (of course) its radio would require that voltage. It would be like putting diesel fuel in a gasoline car.

Oh well.

I have the same issue on a recently acquired Beocenter 7007. Following this sage advice, I'm going a step further and plan to contact Shun Mook, to see if they will make me a proper audiophile lid stay from mpingo wood...

Tighten the spring by twisting it to increase its pre-tension.
If the three claws on the inner holding plastic rail has broken, you must repair this too.

If you mean the middle thing sticking up...guess the ending to this sentence...yes, I'll be looking thru the various brands of epoxy in the garage. There wasn't even any kind of snap, it just broke mostly off but hanging by a thread, then just dropped off. Like I didn't see that coming!

Returning the lid without the spring (fortunately) won't be a total disaster; the lid just feels heavier than before. Chopstick remedy will still apply.

Actually, I suspect this middle finger (a product of Metaphors 'R' Us) was very weak in the first place. Possibly a droopy lid signals this tab is already cracked?

I'm not sure yet whether I will attempt to fix this problem, considering that much more than the tiniest amount of epoxy might glom up the works. If I can return the parts in such a way as to have even a small amount of spring, I'll be happy (and very surprised).

And, when working with springy wire, I always wear eye protection. It can't hurt.

At one point I was thinking of machining an aluminum replacement for the broken plastic rail. But I don't have the equipment for that!

I am having the same problem with the plastic dust cover on my turntable.  It looks like a wire or 3 wires that create a hinge to keep it up to access the turntable.  I am looking for information on how to correct that, if I found out I will let you know.

Thanks for the response, i even thought of having someone with a 3D printer to print a new piece to correct that problem.

Thank you, I am sorry for the late response, I just found where to respond. I thought of a 3D printer to reprint a part, good idea but need someone with experience.
