Sorry Andrew - I meant the programming cover but I think I've figured it out now and have the spring back in place and working again. My 7000 is now fully cleaned and restored and all functions working perfectly again.

Can anyone please tell me the correct orientation to refit the long cover spring on the BeoCentre 7000? I've donwloaded the service manual but it's still not obvious to me! Thanks

Thanks Andrew Careful cleaning and a tiny amount of sewing machine oil fixed both tape drive and turntable. Everything works fine now. By the way, does anyone know what the sticky material is that is used on the plastic linkage to damp the top cover movement on the BM2200?

Problem solved! I rigged a temporary cable from the Beocentre 7000 cartridge output to the DIN phono input on the BM2200 and got good sound on both channels confirming the 2200 was OK. I then traced the problem on the 3000 to a dry joint on the signal cable ground connection at the small pcb inside the turntable. So in summary, my problem was a poor

So now I also have a Beocentre 7000 with working turntable and good sound on S-45 speakers to continue the faultfinding. The cassette deck is not working but I'll look into that later. My plan is to rig a connection from the 3000 DIN plug into the phono preamp board input on the 7000 so that I can verify that the 3000 and its MMC4 are OK. I'll

Thanks. I opened the DIN plug and the connections looked OK - no sign of solder splashes or flux. I re-soldered anyway but it made no difference. I also tried with/without the ground wire on the DIN shell. I ran a separate ground wire between turntable and amp but no change either. I will be getting an old B&O system to play with in the next few

Thanks Martin Unfortunately I don't have access to another turntable or cartridge so I'm just going to have to try to debug this the hard way. I have been in touch with the previous owner of the 3000 who is very trustworthy and says the turntable and cartridge are both good. Unfortunately, he now lives about 500 miles away so I can't use

Thanks Martin. Whilst I'm waiting trying to find a test record, I measured around the power supply and here's what I found, I'd be grateful for your comments: P31-1, -31.53V, 250mVpp sawtooth ripple P31-2, +31.15V, 580mVpp sawtooth ripple (note I swapped over 5000UF caps and this stayed on the +30 supply) P31-3, +33.0V, 50mVpp noisy ripple

Thanks Martin. I have now replaced all of the electrolytic caps and noticed C3 in the power supply had been leaking so I thought I had found the culprit but unfortunately the problem remains. I have also just repaired my Tektronix 465 oscilloscope wich I haven't used for about 5 years (also a cap problem!) so now I can monitor the BM2200 properly

Thanks Martin, I have the original documentation for the BM2200 which includes good circuit diagrams - will the service manual offer much additional information?. In a previous life I was a computer engineer so I'm comfortable with electronics (less so with analogue!) and soldering etc. I notice the 35V supply to the phono circuit is down to 32
