Microcassette Corder Grundig DH2071 Stenorette Vintage Dictaphone

Grundig DH2071 Retro Dictaphone / Voice Recorder which uses dedicated Stenorette Steno-cassettes. This one I found it on Facebook Marketplace for 6 Eur as broken, but actually after cleaning, replacing the belt and buying a Steno-Cassette, I realised was fully working.
This piece was entirely cleaned, restored and fully tested.

Hello! I just bought a Grundig2080 and without a cassette loaded it makes an awful noise and the switches looks sliding weirdly.
Is that something you have also encountered in your model or I should declare mine as broken?
Thanks in advance.

Hi! Well, hard to say. Try to clean it up deeply, especially the internal switches, the one related to REC. It can be that's the cause of the noise.
