Hello,

I've recently bought a Beogram 1102 and have a couple of questions to ask the experts! This is my first B&O system which i'm just trying to fine tune and wondered if anyone had any experience of the following and any suggestions!

1. Firstly the turntable seems to rotate un-evenly and I can't work out if it's just me or if there is a problem? I've checked that the platter (and records) are flat which they are. Do you think it needs height adjusting / levelling? If so, how do I do this accurately and is this done by adjusting the transit screws? I've checked the manual but being a newbie it's not making much sense at the moment and wondered if anyone could explain it more clearly. I've uploaded a couple of videos to Youtube so you can see what I mean about the un-even rotation

2. Secondly, the pick up arm seems to have what looks like 'white rust' on it. I've tried lightly scraping it and it does appear to come off. Has anyone else experienced this and is there a way to clean it up / remove it?

I've uploaded a picture here http://i821.photobucket.com/albums/zz132/richardbell81/pick-up-arm.jpg

Any help is much appreciated! Thanks in advance, Rich

The white stuff is corrosion - the arm is magnesium I think. I am sure you can rub this down but the black finish will be not as good. You could respray with satin black though.

Peter is right about the corrosion, but I have some bad news for you, corrosion signs anywhere on a BG or other B&O vintage products, are signs of long storage without protection. You should open the deck and give it a throughout cleaning and lubricate everything, on steel surfaces where rust is visible clean of the rust and give it a light coat of oil.

More bad news, the under platter, (the pulley where the aluminum platter rest on) may be bend, this happens if the BG was transported or shipped with the aluminum platter in place, it is possible to repair the pulley, but you will need a lathe to do it properly.

Sorry for the bad news, welcome to the forum.

Thanks very much for the advice, although not exactly what I wanted to hear!

What would you suggest to clean the corrosion off with and how would I apply it? What about WD40, Would this do? The general mechanism under the platter seems to have no rust but it is quite slow to get going? Can I lubricate the joints with anything and what would be best to use for this? Apparently it was serviced last year but I'm not so sure now!

You were also right about the platter in being in place during transit, although there was some bubble wrap between the platter and the main pulley. I have no idea where to start looking for some one to fix this, i don't know anyone with a lathe! There is a B&O shop down the road from me but I don't think they will be interested in helping me with A 1970s beogram!

For the pulley go looking for a machine shop, its a 10 min. job to align the pulley if nothing is broken, just remember to tell the machinist that the pulley was pressed down, when bend, so he will have to bring low point up, measuring on the points  the aluminum platter rest on.

Do NOT use WD40 in your deck, use a sewing machine oil or Liquid bearings (Ebay), Clean off all old hardened grease and oil with IPA or mineral spirit lubricate all joints and contact surfaces after cleaning. Use cotton swabs and pipe cleaners to get into all corners.

If the deck still is slow after this, you may need a new belt.

Where are you living ?, there may be a member near you that can help.

Hi there, sorry for the late reply!

I removed the platter and the belt does seem quite loose, and the general mechanism seems to take quite a long time to get going! I think it probably needs cleaning and some oiling.

One question, and I know this is a simple one... how do you remove the flywheel? It wont pull off so i'm assuming there are fixings which need to be unscrewed but I can seem to find them anywhere?

Thanks again,

Rich

Hi Søren,

Sorry to bother you again!

Can I just ask, what exactly do you mean by the 'pulley'. Do you mean the flywheel that the platter sits on?

Thanks

Yes with the pulley I mean the flywheel.

To get it off, you may have to pull a pin that secures a gear to the shaft of the flywheel, way down at the end of the shaft.

My turntabe was not running level and the records were scratching the aluminium. When I had a look under the platter, I found there was one sprung clip had come off and there was no support at that point. I fitted the clip back and all was fine.
