hello colleagues. A few days ago I bought my first turntable. Grundig PS 2500. Everything was fine until I saw that the needle was covered in dust. I touched my finger and the needle was gone. The AT71 cartridge is there. the question whether to buy an AT71 cartridge and that's it. will it be possible to change to another no. orthophone? worth investing what is the best way to clean the needle?
Why not change the stylus assembly?

Clean the stylus with a fine stylus brush or artists brush, but always brush from rear of stylus to front - never in the opposite direction or you are in danger of damaging the cantilever that carries the stylus.

It's best to buy a 100% original Audio Technica stylus - like the one to which I linked.
A cheap non-original stylus may not give as good a result as a manufacturer's original, but there are some quality copies on the LP Gear site e.g. the ATN71E elliptical stylus.
The AT71 matches your turntable well, so I suggest you stick with it.

Do you mean you have a short circuit in the turntable's captive RCA cable?
Any decent twin shielded/screened cable will do as a replacement, see attachment.
I'm not sure what you mean by "Can I cancel the channel leading to the preamplifier?" - please explain your problem in more detail.

If it would be helpful, the service manual is available to download from here:

Your turntable comes fitted with a twin RCA cable and a separate ground wire as shown in the first image.
It should be connected to the phono preamplifier as shown in the second image.
Replacement RCA/ground leads are available to buy, if that is what you are after.
Here's an example: https://saveltd.co.uk/quality-deck-...o-lead--earth-cable-audio-technica-6405-p.asp
If this does not answer your question then please come back - with photos if necessary.

Do you mean is it a lot of work to replace the twin RCA/ground cable?
I could talk you through the process if required.
P.P.S. If necessary (if you are still experiencing hum or buzz) you can connect a second ground wire between the phono preamplifier ground post and the main amplifier ground post. I did this with my setup.
