ModeratorGenerally:
Without a record on the platter, the carriage with the tonearm etc. will not move in. The platter will just spin for a few seconds while the record sensing system operates.
Using the search buttons will only work while playing. – Not from standby.
And when you use them the light comes on and you must hold the buttons to move the carriage to the desired position – then press play to resume playing.NEVER use anti-static mats with any Beogram.
1. It’s not necessary. (All alu platters are anti-static, and the ones used on tangential decks will create a soft
vacuum under the record).
2. It disturbs the tracking angle because the record sits higher. This results in distortion.
3. The record sensing system will not work as intended, which could result in a ripped off stylus if the deck takes the mat for a record. This could cause a vacuum in your wallet.Martin

ModeratorThe drive suspension kit should be available again shortly from Danish Sound Parts.

ModeratorWould the main problem be reflections of the sound produced by the needle playing the record,
or acoustic feedback from the speakers to the record?The first I don’t believe one moment. And there would be many other things involved having greater effect anyways,
like:
– Do you wear your glasses or not when listening.
– Do you drink red or white.The latter I can vote for. We ran a quite powerful mobile discoteque many years ago.
At high playing levels the record could take up enough energy from the moving air to jump the needle.
Definitely perceptible.
Closed the lid when playing – problem solved.The warming up of old rubber suspensions (MMC20CL in particular, in my opinion) also provides a very much perceptible difference – to the better, if you ask me.

ModeratorBad or lose connector for the keyboard?
Cracked solder joints?Martin

Moderator33uF or 47uF is not important. The important parameter is the capacitors filtering properties.
The capability of playing CD-Rs lies mainly in the focus travel and the focus setting (don’t mess with this unless you know exactly what you are doing!).
CD-R is not a standard format. Even if most CD-players will play them, don’t expect them all to do it.
A normal factory CD has the info-layer sandwiched between two layers of polyester.
A CD-R has the info layer on top of the disc. This puts the info further away from the laser lens, and the laser needs
to be able to focus on this longer distance to read the disc. Not all lasers can do that (or were manufactured with this in mind).The kit from Danish Sound Parts has all caps for the servo board.

ModeratorThe noise could also come from the amplifier.
Which amplifier are you using?Martin

ModeratorIf would be helpful, if you would state the location.
Country as a minimum. And also your idea of the price.Martin
Dillen
ModeratorHave you tried using a different pickup cartridge?
Martin
Dillen
ModeratorIt could be helpful if you’d let us know where the items are located (country as a minimum),
and also if you have an idea of the price.Martin
Dillen
ModeratorWhich amplifier are you using? And how are they connected?
Does the needle track the record?
Can you hear sound from the pickup cartridge itself when playing a record, if you put your ear close to it?Martin
Dillen
ModeratorThe relay is pulled when in standby. This can be confusing.
If it does not release when ordered, the amplifier will not be powered.
Check the relay driver circuit. A shorted transistor here would not be a first.
If you already suspect D2, that would also be a good place to start.Martin
Dillen
ModeratorCheck the start switch. These switches are known to oxidize and lose contact, particularly if not used for a long time.
Check for cracked solder joints where connectors are soldered to the circuit board.
All OK? Check voltage on motor leads.Martin
Dillen
ModeratorRecord on the platter?
Martin

ModeratorYou can calculate the voltage drop across the emitter resistor and use that as the target setting.

ModeratorAs mentioned above, parts are usually no problem.
What is needed here is a good repairshop or a skilled DIY/hobby-repairer.
There must be some in northern Italy.Martin
Dillen
ModeratorNo. The start-up sequence is all mechanical.
Martin
Dillen
ModeratorYes, you can set the tracking force as shown in the user manual.
But check your stylus first. It could be dirty. That’s one of the most common causes for distortion together with bad cantilever suspension.Martin
Dillen
ModeratorSounds like a problem with the tracking system.
It’s a opto sensor and a lamp, with an interrupter in between.
Either the lamp has died or the sensor has gone bad (they can deteriorate internally).
Some times both.
(Electronic faults in this circuit are rare).The Molykote you mentioned is a fast-hardening coating.
That’s not what you want here. You need a long-term (decades rather than weeks),
grease to make the carriage move smoothly and jerk-free.Lamp, sensor, correct grease is all available from Danish Sound Parts.
