Just tried the headphones once more which does not seem to work properly either - the sound is louder in the left channel, more high tones, less bass than the right channel which is lower and more bassy.

Suddenly I works fine with headphones, nice sound in both ears, then it suddenly doesn't -  often in relation to fast forwarding/backwarding of the tape.

Sounds like a fault in the Beomaster - possibly in the DIN connection panel. Does a CD player work ok? If so, remove the two extra pins in the Beocord 5000 DIN plug, and then attach it via the CD socket and see if it works then. You will need to select CD on the Beomaster and work the tape manually. If this works ok, the problem is the socket panel, I would suggest.

Pretty nice diagnostics! When I plugged the Beocord into CD-socket, it worked fine. Then It's the beomaster. What is wrong with the tape socket, tricky to fix?

All tips are welcome! Seems now that the problem was not quite solved. The Beocord still, while playing, suddenly changes it volume especially left channel with symptoms asdescribed above. If I press STOP, the PLAY the Beocord sound normalizes again. this happens every 3-4 minutes while playing I think, it happens when connected to both CD and Tape socket....
