A good idea would be to prove which of the two units is causing the problem, i’m assuming you dont have access to a different amplifier? during my dealings with the Beolab 5000 ( I have restored 3 or 4 over the years) I discovered that the AUX connector is wired slightly different to the other DIN inputs…strange I know, If you would like to know more I will dig out the circuit diagrams and post them here.

If your getting 4.7vdc at the points above then your getting the correct voltage to energise the solenoid, unsolder the wires and check the resistance of the coil…it may be open circuit which could be our probem…let us know the reading..

All reassembled and the hood in place….sounds as good as when it was new! all four now complete…..hopefully this thread has entertained and maybe even helped others along the way.

Pulley arrived today along with the control panel lamps….should have taken a pic of the pulley in place, it can just be seen to the left of the control panel pic ;¬)

Cant beat the original hardware in my “black and white” world…..sold complete with all the service information required to maintain it through it’s lifetime…..designed to be maintained/repaired by pretty much anyone with a soldering iron…..over engineered? yes delightfully so…buy anything today and all you get is a QR code on the box inviting you to download a quick start guide in twenty languages 😲

This done I had to have a listen……..all sounds and looks healthy.

This done, and bearing in mind the numerous adjustments made, the pickup arm lowering limit needed checking and as suspected it was falling below the level of the lower ridges on the platter….disastrous for the stylus should the detector arm fail and allow a drop onto a platter with no disc……easy adjustment which did have to out followed by setting the stylus force for the SP15 which should be 1.0 gram. The dial was set around 1.25 and sure enough my scale did read above 1.25g….I struggled to get a good image of these, set it to 1.0g and to be fair the scale on the pickup was very close to the 1.0g setting…..

Got the platter level with the aluminium trim and also central to an acceptable point

I’m taking the view that the 8000 is very similar to the three off 8002’s  that I have very recently worked on….one of which had that self same problem, firstly I would suggest you upgrade to silver which will give you access to the service manual for this machine. If you read my thread  “Beogram 4000 and also BG8002″ you will find the section regarding a tone arm that wouldn’t drop (feel free to look….3 people have done so already) check you are getting the required 5.0 vdc to the solenoid when it reaches the drop point…..the thread details where to measure assuming you have a meter to do so…..let me know

the floating chassis also requires some adjustment to bring it flush to the deck plate…

back of the platter needs to come up a little….some adjustments later this was the best I could do

One of my least enjoyable adjustments is the platter height, never have got it bang on despite trying many times on many machines…there just never seems to be the required adjustment afforded by the “slogger” in the threads between the bearing and the lock nut…the theory is good but in practice is very tricky to achieve…my tip….ensure the set screws are protruding a good amount below the lock nut to give them the most leverage…

Quick adjustment of the 33rpm trimmer I replaced, was a little high but adjusted down nicely….the Beolovers patent tacho I purchased some years ago helped give the required accuracy.

Once satisfied there’s nothing for it but to commit to the bend, there’s only one chance…..will need to apply glue and epoxy but given where we started I’m calling this a win.

On with the dust cover repair…the epoxy has cured and after a little cleaning up im quite happy with the joins so time for the new trim, getting everything central is key….

Voltage for drive motor was i little bit out….adjusted slightly, should be 6.5v RMS or approx 18.0v P to P at 43hz with a clean sine wave.

Set up the electrical adjustments…slow slide transports left and right, should be between 2.5vdc and 3.0vdc. Looked good to me so went with both as is.
