Beomaster 4400 rosewood.
Mint condition.
Completely restored.
Not cheap.
PM me if you are seriously interested.

Perhaps the spindle hole in the large pulley is worn out of shape from using a wrong belt (too tight)?

Martin

[Dillen]

A wrong belt can indeed mess things up. And it can even damage the delicate sinter bronze motor bearings.
It’s impossible to say if what they sell will work. I have seen countless wrong belts sold everywhere.
Correct belts are available from Danish Sound Parts – also the wedge-shaped one for the carriage motor.

Stay with the original and have them refoamed.
They are unique for these models.
6,4 Ohms if I remember correctly.

Size is not everything when it comes to speaker drivers. Look at the list of T/S parameters.

There should be no nylon washer – but in some Beocords you will find a bronze spring plate.
Does the large pulley wiggle on the metal spindle?
Has the thread on the spindle been damaged?

Was this Beogram moved to a different mains voltage area?
Replace the transformer and make sure it is set up correctly for the actual local mains voltage before connecting mains.
Having siad that – if the Beogram suffered an over-voltage situation, some of the electronics may also have been damaged.

Bad opto sender IR LED at the threaded shaft.

Rosewood it is.
Teak is lighter and has a finer grain pattern.
These speakers won’t ever degrade from foam rot, because no foam was used.
They are excellent speakers.

It was not meant to be disconnected.
I always desolder the connector from the board.

Normally, these remote controls need very little attention.

Check for excess ripple on the supply voltages (bad filter capacitors).
If your CPU module has an electrolytic capacitor near the edge connectors, replace it.

It’s an oil stop.
It prevents oil from the bearing creeping up the spindle to the pulley.

I would never increase the current limit of a fuse significantly.
Sometimes you can find 315mA fuses rather than 300mA. That would be OK.

Martin

[Dillen]

Just a side note:
The 47uF axial capacitor on the subchassis must not rest on the black plastic support.
There is no room for that. The subchassis movement will be restricted by it when the Beogram is assembled.
It must be arranged like the original – down on to the metal.

There are four holes provided for C24 (to allow for components with different pin spacing).
Going from C27 towards C29 they are negative, positive, positive, negative.
Note that the two negative holes are connected together through the jumper next to C1.
This can often cause confusion.

Martin

[Dillen]

I am not aware of any modern replacements.
You could ask at Danish Sound Parts.

Martin

[Dillen]

Nothing missing or broken as far as I can tell.
The lit sliding pointer just leans against the rails, it doesn’t grip them.

Martin

[Dillen]

Isolating the secondary merely means disconnecting everything on the secondary (load) side of the transformer.
Doing this will confirm that the humming is caused internally in the transformer and not as a result of a too high load.

Replacing the transformer is the only cure.
Having siad that, the humming transformer will continue to work technially with no problems for many
years on, but of course the humming can be annoying.

Martin

It can be difficult to spot the crack in the worm gear.
I have seen this several times, and I suggest you look again.
Or simply pull off the gear and glue it back on using a good 2-comp. epoxy.
