You'd better take it back, if he said there is nothing wrong with it!

Usually people sell things because there are problems with it. It is very
rare that these things come used with no faults. If a piece of equipment is
working well, there is no reason to sell it, unless it is from an estate
sale or bad dept problem.

To service it, you will need more than a soldering iron and a screwdriver!
You will need some test equipment, the service manual, and a fair amount of
service experience. The hum is most likely from some bad caps in the power
supply, and maybe some decoupler caps that have gone high in ESR. You will
need an ESR meter to properly test the capacitors.

As for the FM problem, fixing the hum may also fix this, or there may be
some front end problems. The front end of the receiver is fairly complex to
service, and someone going in that area without the knowledge of servicing
RF circuits will probably do more damage than good.

You would be best off getting an estimate from a B&O service rep, and if you
find it too expensive to service, then you will have to swallow your losses
if you cannot return the set to the vendor.

Hi All,

I recently purchased a Beomaster 2400-2. The guy I purchased it of
assured me it was working fine, but when I got it home it was a
different story....

There seems to be a loud humming noise in the background, this seems
to be present on all the inputs as well as the radio. I plugged in a
set of headphones (thinking it might be the speaker outputs), but the
hum was still there.

The other problem is with the radio...FM5 seems to work fine (despite
the hum) but all the other FM presets have no sound FM1 to FM4 (when I
turn up the volume to the maximum, I can hear them faintly)

I am just wondering if anyone has had any experience with these
systems?, and could describe what the problem may be.

I haven't had much technical experience, but I am adventurous with a
screwdriver and soldering iron.

If anyone has any schematics or any instructions on how to dismantle
it, that would also be great.

Given the problems, it is still a cool looking amp. I was gutted when
I discovered that it didn't work as I had been after one for quite a
while....

Any help appreciated,

Cheers,
