Hi,

you have done a lot with the electronic, but this seems to be a mechanical problem. The arm must lift up, when you unplug the deck, I mean not only when in stop mode. There is a solenoid, that can (should) slide back and forth horizontally. Only for "play" this solenoid is active and lets the arm drop down.

I was looking at that Coil cylinder and from what I can remember from when I worked on it last time, that is supposed to move freely in and out. Correct? if so, it's not moving and is stuck in the out position against that copper or brass looking stopper. I will take some pictures and will post them here later today.  Hopefully it's just a transistor that has failed since it's controlled electronically or just a bad connection between the ribbon cable connector and ribbon cable.

I do have another BG 8000 that I was going to repair a while back but just haven't had the time. I did buy the Tacho disc and cap kit from Dillen already so I will get to work on that one. I hope that one is good working conditions meaning everything else works and no major issues.

Sorry, but as I said before: the arm has to lift up, when no current flows. If a defective transistor should be the case, the the arm should definitely lift, when you unplug the deck from mains.

Right!

The Arm is down, when the coil has moved to the back and comes up when it moves to the front (sitting in front of the player) Additionally it's a damped movement.

ProGram,

Thanks for the help and info. My next question is, Can this part be repaired? or does it have to be replaced? Could it be just a simple lubrication to lossen it up and move freely again or once stuck there is no repairing this component? The reason I ask is that I don't the exact condition of my other BG 8000 as far as the bearing thrust plate is concerned.

The guy I bought it from said it would turn freely for along time once turned by hand and he did pack it the way I asked him to to not damage the bearing. I could always swap them but I would hate to go through all this recap, resoldering and everything else again. I may just replace that part with one from the other. I just need to check it out and may have to go with the other BG 8000 I have.

Generally: yes, it can be repaired. Strictly speaking, I cannot understand, why the coil remains in the position. Must be the lubrication that has totally dried out. But the deck is not old enough actually for that kind of fault.

I have complete tonearm of a 8002 as spare part for comparison, should be no difference in the lift section

??? He was talking about the platter 😁

yes, I meant he seller told me the platter spun freely and for a long time. So from that statement hopefully the Thrust plate/breaing are fine and that I can use this second BG 8000 I have if that coil in the malfunctioning deck is unrepairable. Just don't understand that how it could work perfectly for two albums and then just take a dump like that. Oh well.

Update: Today I finally got back to my Beogram 8000 arm lift problem. It turned out to be the coil some how got turn a little where the wires that go to it were turned upwards and it some how got caught or hung up on something. It's back to working like normal again. I saw that the coil was more towards the front of the housing. I tried to move it back but it didn't move, I moved the the coil downwards then it started to move freely, I put the cartridge back in and it's lifting/dropping like normal (still drops a little fast but nothing to worry about).

That's good news. Sometimes when you are away from a problem you can rethink more clearly when you return.
The Beogram 8000 lowering is circuit controlled while the old Beogram 400x lowering had a mechanical dampening system. You hear a lot of the Beogram 8000 turntables lower too fast. Mine is currently in that club. However, there are times when it lowers gently as expected. That means it must be some issue with that circuit. At some point I will pull that turntable back to my workbench and try to diagnose it but I just don't have the time right now.

I can't remember who was here in the forum that said they replaced every component in that circuit and it still didn't fix it, the arm still lowered at the same speed as before. Mine does the exact same thing as yours, drops a little fast but sometimes slower.

Well, it's time to start restoring my other Beogram 8000. I already have the cap and tacho replacement for it, so hopefully everything goes well on that.

I'm glad I bought a second Beogram 8000.
