Yes again my thanks to the help of all of you. Olly has a good memory that I had 3 non-functioning tables to begin with, and one had to give up its life for the other two. I now have a second one almost working but am dealing with issues with a platter motor I believe that is not stable. It had the central pole stuck and needed to be taken apart to get it loosened up and I think I might have done some damage to the brushes that are at the base of the motor. The rest of the table seems to function properly but needs to be properly adjusted and set up. The table I have been posting about was quite a mess so the second one was much easier to fix.

Warm regards,

John

Really good to hear that John!

However many typical problems we'd go through, there's always a surprise somewhere... good work sorting that out

As a final note to all of you who helped with the restoration and trouble shooting of this turntable I wanted you to know that there is now another fully functioning Beogram 4002 turntable out there in the world. Jacque was correct that I needed to tear down the table to get at the lifting arm to fix that problem. It turns out that the lifting arm was corroded to the shaft it was supposed to rotate on. So instead of rotating on the shaft the shaft was partially rotating in the housing, I was amazed that it was doing that at all since that pin is supposed to be fixed and not rotate. It took some time to get everything adjusted but all seems to be working properly now and I have been listening to records on it with no sign of a problem.

Thanks again,

John

Hello Jacques,

I was looking for screws on the side of the assembly and did not realize that it was the top two to the left of the sensor arm, so I think I have got that now. Regarding a circlip tool, I will probably need to get that from an online source since Boise, Idaho does not have that many options. Can someone reccomend a source or a specification I should be looking for regarding the correct size tool I would need to remove the circlip?

Regards,

John

Hi,

There is no need to remove anything before doing it.

Just follow the procedure I give in both posts (on page 2 here you'll find the link to the other one) just being careful of those thin wires!

Patience and the circlip tool (quite cheap, can't do without) will lead to success I'm sure, provided you haven't touched any other setting that is... If so you will probably have to adjust again... back to the old settings!

For me it was indeed arm 220 and arm 193 as well. Don't touch part 236!

Hello Jacques,

I am afraid my friend you are correct, but I do fear this teardown. You supplied an exploded view of the tone arm/sensor assembly earlier in a post, can you tell me where I need to start first, it is the lifting arm (part 220) that is the problem I think. Should I remove the adjustment bushing (part 236 in the manual) on the right side to start?

Hi John. You know what to do, don't you? Yes, yes it is a pain to do but then you know I'm right!

Be brave and go ahead!

Well I had good intentions to get some photos on the forum of the table that I have been working on but I am now having some mechanical issues with the tone arm rising all the way to the horizontal after playing. It rises part way to the horizontal position but goes not further. I can manually push it back up so it may mean some work with adjustment and hopefully not a tear down to clean up the old lubricant.

Hopefully I will work this out soon, I am so close.

Hello Jacques,

I have not forgotten the pictures I just have been pulled away by my teaching at the university and have not been able to get to it. Tomorrow is Saturday here and I will do it then. Sorry I don't have a video camera but you might have been joking anyway.

jfrancis:

what would you like to see, action shots of the turntable possibly?

John

Yes, plenty of close-ups and possibly a small video!

Hello Jacque,

You do deserve any photos you would like to see, unfortunately the last 2 nights I have been making repairs of a different kind, plumbing which I hate doing. The faucet in the kitchen decided to leak. Unlike electrical problems you end up with a wet mess if you don't get it right. I am pretty good with a camera so what would you like to see, action shots of the turntable possibly?

Well done John!

Any photos please?

After all that was said, I think we deserve it!
