Move the doors on the string.
Losen the small clamps, move them and tighten them again.Martin
Can you hear the sounds also if you play a record with the Beomaster turned off or its volume at zero?
Martin
Bad pickup cartridge?
The faint sound you here – does it correspond to what you what expect to hear from the record?Martin
Is the clack and scratch sound coming out of the speakers or from the Beogram?
Martin
Capacitors working with negative voltages will often have their positive pin to ground.
Check before assuming it’s wrong.Martin
For connecting to the Tape input you will need a RIAA.
The Phono input, however, should be at correct level – unless the internal RIAA in the
Beomaster has been disabled. It’s not that unusual to see. In that case, you should only
hear very low signal, and very treble-rich, because the RIAA correction is missing.Martin
Beocord 3500, 4500, 6500, 7000 were all produced with both drive versions.
As were Beocenter 8500, 9300, 9500.As mentioned already the two drive versions are very different mechanically and not interchangeable,
but I can’t tell any difference in sound quality between the two versions either.Martin
The drives are not interchangeable.
The controllers are also different.
– And the controller holds all the alignment trimmers etc. Setting all this up to a new drive is a HUGE task.
I would recommend keeping paired drives and controllers together.Is there an issue with a drive?

You must take off the black bands (pull them a little to release them from the potentiometer slider).
Then take off the two wire springs, one each end, and open the clutch box.Martin
The small “couplings” or what shall we call them are held by snapping in to indentations in the hexagonal shaft.
Just pull.Martin
The thursday cigar, apparently, was of a better quality than the friday one.
Nice find!Martin
Note: Some Beolit models have positive ground.
This can be a problem in that most BT modules have common grounds for power and signal,
thereby shorting the Beolit power if used on internal power.Martin
Will your Beomaster play radio or any other source?
If your record player has a preamp, and it is active, you could try connecting to the TP2 inputs and select TP2 as the source on the Beomaster.The PRE-AMP sockets are outputs from just before the internal power amplifier. For using an external amplifier.
Martin
Yes. But I won’t say.
I have one just like that – got it from you. 🙂Three rolling stands in one photo. You don’t see that every day.
Martin
It should connect to the Phono input. Either the DIN or the RCA sockets.
Then select Phono as the source on the Beomasters remote.
If no sound is heard from the record player (and the Beomaster will play radio etc. fine), there must be a problem with either the record player, the cable/adapters or the Beomasters phono input.Martin
By back panel are you referring to the black grill that covers the connections? If you are it is only held by gravity. There is a stop piece attached to the underside in the middle of the grill piece that might have gotten stuck down.
The black grill (with sockets etc.) is held down by a plate-type bronze spring.
Just pull up. It’ll snap free.Martin
And apparently, some ICs were replaced as well.
I may be able to find a working module in the dungeons if needed.Martin
