The trimmers on the main board are prone to failure and the symptoms of that are as you describe. It could also be the motor itself in need of cleaning and lubrication. When playing, try tapping the motor housing gently using f.e. a pencil, if the speed changes the motor will need servicing. This applies mainly to the DC motor versions. Martin

Could be that the two metal line-in/out bridges are missing in the connector bay. Martin

Thanks for the comments and suggestions. The AGC components seem fine though I will be replacing the related capacitor regardless. Still, a constant low AGC line should only keep the amplification high so I doubt an AGC fault in this case. It will of course be checked and the IF alignment will be up next. I will have to make up a tool to trim the coil

Wonderful collection ! Martin

Genau, Muterelais kaputt ! Martin

Please don't mix up boards from Beogram 8000's and 8002's, they are different. Could also be a fault in the tachodisc opto sensor in your deck or the wiring around the chassis. Martin

Without a working sample and no immediate experience with servicing this particular set, it's a bit hard to tell what to consider normal and what to expect. However, I would think that for a normal listening volume, the volume control would have to be somewhere around its center position so even if this is merely a 3-valve construction (not counting

Thanks to Chris (Medogsfat) who very kindly helped me to a new output transformer. Your help is greatly appreciated ! With this part, I will hopefully be able to get the output stage working as it should. The original transformer was scrutinized but no obvious faults could be seen, the way too high primary DC resistance however, proved that it was indeed

Strange fault indeed. Can't you find out whre the commands come from ? Surely something must be shorted somewhere. Martin

I agree, they should be replaced. 3300uF will work fine and actually improve the output stage's bass response and damping factor a bit. Remember to polarize them correctly. Martin
