I would guess that the opto part is faulty - see here .

Dave: If it's sunny over there lay it upside down on a grid or a towel in the sun... It's snowing here right at the moment - I guess that is not really sunny. Back to the topic: I would leave it as it is - I've tried to clean speaker cloths several times and they always look worse than before afterwards.

I'm finished! Well, at least as far as possible. I have repaired all three tonearms and was able to build two nice working & looking units with these. Sadly the third unit (which is made from the worst looking parts) is missing a part. The mounting for the tonearm is broken, but I thought this could be fixed as the broken off part was included

Today I finally got to work on the second unit. This one was even worse, seems like they used another type of glue on that unit (that sort of cable channel and the soldering points were originally covered with glue that had to be scratched out) . I needed hours to remove it and that was just for the plastic part...the part of the cable channel that

I think that one is even in better shape than my Beomaster, so I think I will take it. I have sent you a PM.

Thats a great offer. I am very interested in that one, as I still need some other parts for the 1400 (some switches are not working correctly). I would gladly take it if shipping to Germany is not excessively expensive.

I think I would be a bad neurosurgeon with needing about two attempts for each cable and breaking off parts. Actually I planned to build one working unit out of three broken ones (as on one unit the tonearm was only broken once), but now that I found a way to fix that fault I will repair them all. By the way, stripping off the shellac is not quite necassary

Looking for a tuning slider from the above model. Maybe sliders from Beomaster 4401/4000 or from one of the Beocenter versions could work as well. I would prefer the tuning slider (with the adjustment wheels), but one of the other large sliders (Volume, Bass, Treble, Balance) would also work. I need it for an otherwise great Beomaster 1400 (the 1987

Just wanted to say that it actually worked (at least I have finished unit 1 of 3). As Chris said it is a thing one will never do again. In my case the tonearm was even broken at two points, so I had to disassemble the complete tonearm and reroute the cables. The worst thing was scratching out the glue in the mounting for the pickup....and then I even

Thanks! That is actually the thing I was searching for. I already had a look at the service manual, but somehow I did not see that one. Could it be that the service manual is missing a page? That circuit is only shown in the extra part of the manual referring to the Beogram 2000 & 5000. In the 1800 circuit diagram th at board is completely missing
