Mains fuses Beocenter3500

Hi

I'm just setting up a BeoCenter 3500 that I have just bought and it has a two pin continental plug on it. What fuse should I use for the 3 pin UK plug that I'll be fitting please? I thought either 3 or 5 Amp. I tried it with a shaver adapter (1A fuse), but that just blew straight away of course.

Thanks very much

I've been looking online and it seems like a 3A fuse would do it. Looking forward to getting it powered up to see what it sounds like!

Good luck with your BC3500. I believe it has a direct-coupled amplifier (like the BM3000 of that era) that sounds amazingly transparent and dynamic compared to later models like the BC9500.

Thanks - there are two 1A fuses in the back and I think one or both may have gone so I've ordered some from Amazon. Hopefully will get it running soon - I also heard good things about the sound quality and it certainly looks the part!

3 amp should be adequate,and you can get an adaptor to convert the continental 2 pin to U.K. 3pin too.

(not a shaver adaptor,a proper jobby!)

Nice unit indeed,but it will almost certainly need some tlc to restore it to full working order.

Lot's of experienced users/restorer's on site,lots of parts available.

We'll be interested to hear how you progress,and ready to advise in due course

Thanks Nick.

I bought it reconditioned from a B&O specialist who has been very helpful. I've got some 1A fuses coming today so I'll try those first. I've got a UK-Vistor adapter for now with a 13A fuse. If the fuses don't fix it, he's suggesting I look at the power supply transistor (I think that's what it's called) that is near the cable entry point to see if the screw that fixes it down is rusted. Fingers crossed. It's a lovely piece of kit so I hope I can get it going.

What?  A power supply transistor? - Where?
And rusted? - What?

- And that came from a "B&O specialist"?

Sorry, but that's a load of rubbish!
All of it! 

Mains fuses in the voltage selector housing are 2 pcs of 1A slow blow.
If your Beocenter has these, you don't need one in the plug.
In other words you can pick a larger one for the plug because the internal ones will blow first in case of problems. 
If your Beocenter doesn't have the fuses in the voltage selector housing (or doesn't have the selector housing at all), you could choose
to fit a 1A slow blow in the mains plug. 
If it blows (because of high mains) try fitting a 1,3A or something thereabout slow blow if you can. If that one also blows, there's a problem with
the Beocenter. (and tha'll most likely be a shorted rectifier).
