Welcome to Beoworld!

Nothing can be said from the pictures you display here. You really need a microscope, a good light source and some experience to do that. I use x20 magnification, more if I can’t decide. The worn surfaces are this tiny!

Listen to a distinct lack of high treble. A dull MMC is a worn one.

Ça marche Yann.

Yup, the idler is definitely the culprit for this noise. The usual flat spot plus hardened rubber. Nothing to be done here, just have it redone by a competent company. All three have to be done, by the way.

Meanwhile, you can swap the noisier one with the one at right.

Never mind the belt, but yeah, it’ll need to be replaced too. It’s a bit loose.

The rattle is not normal. Just feel if the CD is clamped completely. When it starts turning, unplug the player and feel whether the CD has some play as regards to its platter.

Cheers ?

Funny that I should still appear as a bronze member Guy, by the way ?

Here, replace those already.

Leave the large silver caps alone, and check the others that supply the different voltage rails.

Two things if the transformer gets hot:

– Is it 220 or 240?

– Check power supply caps. I had a 5500 with a nearly shorted one (Sony branded) that made the transformer thermal fuse melt.
This might eventually happen to yours.

Leave the motors alone.

I really enjoyed the museum tour. Almost like being there!

Thanks Steve ??

Hi,

It sounds as if something is rubbing. The rotation should be silent. Are you certain that the disc is properly clamped?

[chartz]

Yes, great machine with a mellow sound, really nice. ??

[chartz]

I agree with Søren (hi!). Do replace the aforementioned caps and check for bad solders. So is it just on records or not?

[chartz]

It’s cheap if there’s no rust anywhere and if the heads aren’t worn out. Bogen heads are fragile and soft.

[chartz]

Ah ok, here BC often means Beocord. My bad, I should have watched the videos. So no.

[chartz]

Please moderator erase.

Belts and tyres. You have to do them all.

The place you want to buy from is called Beoparts.

[chartz]

Yes, the Bogen heads can be defective. Not worn necessarily but electrically defective. They don’t like old capacitors at all, so if you find an old machine that hasn’t been powered on for ages, don’t try it. Replace capacitors on playback and record circuits then go ahead.

The BIG problem in those decks are the idler wheels. Normally they should be completely silent, but after all this time they harden and become intolerably noisy. They really ruin the experience, hence my preference for Revox machines over Beocords or Uher machines, which were good, but had only one Papst motor.

[chartz]

Yes, very useful! Thanks ??

[chartz]

You can’t. But are you certain that the laser is toast? Very unlikely.

The laser head should be near the centre – its normal parking position – and the end position switch engaged.

Investigate this. Try to manually slide the laser sled towards centre (done that?, it isn’t clear) and see what happens.
