As already suggested, check the thermal fuse in the transformer as the first thing.
Next, check for cracked solder joints at connectors and at the large capacitors at the back.

Plastic lacquer?
I would imagine that could cause static problems.

You can’t do ohm readings on a powered circuit.

Martin

[Dillen]

Is it completely dead?

Martin

My first thought was also, if you had the trimmers mixed up when you fitted them.

Martin

Very nice finds, indeed.
Here is a Beogram 5000 in palisander (red label), just to give you an idea what it looks like.  🙂

So it is.

It’s an MPX filter. It grounds remains of the stereo pilot.
You can fit any good similar filter – or ask at Beoparts for a good used original part.

I’m still here, but far from as active as previously.
Others have left altogether and found other places.

This thread is perhaps not the best place to discuss it, but I have my reasons for now visiting merely a couple of times weekly rather than a couple of times hourly.
I can only imagine, that other members, be that  “surviving” or previous, have their reasons as well. Perhaps some or all of the reasons are the same.

And I don’t think it has anything to do with the “misunderstandings” mentioned above, really. They merely stirred things up a bit and added energy to the forum life.
But I agree, they seem to have gone as well.

So it actually works for a brief moment?

Martin

Check C9, TR3 and TR4 in that order.

Are you comparing a B&O cartridge with 30-40 years old rubber suspension with something factory fresh?

Martin

[Dillen]

Can we have DC voltage readings on TR1 and TR2 B-C-E respectively, with the Beocord out of standby?

Martin

 

[Dillen]

No.
Looks more like something from Philips or perhaps subbrand DUX.
Scandyna could also be a bet. Their 1702-1 was quite a rip-off in many ways. Can’t really tell as the platter is not visible.

Martin

Thanks, Jacques.

That PCB needs a full restoration.
It still has the original capacitors, which will be bad by now, and the original, now badly oxidated, trimmers.
With all that still in circuit in can be difficult to point to a specific culprit component.

Had the PCB been completely restored, and still failing, the reason could be a leaking diode or transistor.

For potential takers it would be nice to know where in the world it is located.

Martin

Beomaster 3500 has no timer functions and it doesn’t support two-way remote control.

Martin

[Dillen]

It would perhaps help, if you’d give us an idea about the the price and where in the world they are to be picked up.
