Hi, I just bought a beomaster 3000 tuner amp and plugged it in and it worked fine for about twenty minutes, I fed in my PC soundcard output and played some tracks from Spotify. Then it just stopped, no light and no sound, no life at all. I've tried a couple of adapters for the two pin plug and also define rent mains outlets. It no luck. Help please!!!!!

You mention 'the 2 pin plug'.  Where did you get this BM3000 from?  Did you set the voltage for the UK on the selector on the rear panel?.

If completely dead, sounds like a fuse issue or mains transformer.  Any smoke or burning smell?

Thanks for the reply Dave! I got it from the UK and I've just looked on the back and there doesn't seem to be a switch but above the antenna details it says 240 60hz  there s a king of recessed cover next to the details but no switch and I can't make the cover if there is one

Oh and when I opened to package there was a very slight smell which I assumed might be normal, it was very faint

OK, I assumed it was the 1970's BM3000, but what you have is the 1980's BM3000 then.  What type number is it?

An original GB model then.  Not sure why it has a 2 pin plug on it then as UK has 3 pin sockets!

It may have overloaded and just be a fuse issue.  Hopefully someone here can either suggest someone locally to look at it or if yourare handy, the service manual is available on Beoworld for Silver and Gold members.

Ok that's helpful Dave ... I have the service manual, is there an internal fuse around the power supply? And also, should the u it be earthed, the lead looks original and the two pin plug is solid so it's doent look like so,ethi g someone's put on later

I think it's a T-1.6A 250V slowblow fuse.  The Manual is the same as the BM2000 with an addendum at the back for a BM3000.  The fuse should be clear to see and identify but check in the manual again.  Also, if you open it up, check the wiring to the mains transformer - is it connected for 220V or 240V?  I think the 2 pin plug may be original.

Dave could I bother you again please? Wi out wanting to sound too dumb!! What might have caused the fuse to blow? I had it plugged into a socket with surge protection but there are other devices plugged into it as well. Also does the amp not need an earth at all? I'm used to systems needing an earth strap, I have a beogram 2200 turntable and needed to earth the DIN outer to the Denon amp earth strap to stop mains hum. Thanks in advance

I'm not an electrician but I suspect that it was an internal component failure - not from a 'power surge' or the result of anything else connected to the surge protector/outlet.

These systems are over 30 years old an component failure is normal - electrolytic capacitors, transistors, diodes  etc are all prone to failure due to age.

Some turntables do need an earth strap as you describe to prevent hum.  The BM3000 must be perfectly safe if it only has the live and neutral leads to mains (I haven't actually got one so can't check) as this was how B&O would have made it.  Presumably double insulated.

Without opening it up, you can't find the problem.  Once opened you may find leaking capacitors as the problem.
