Makes noise when turned on

Came from a house clearance - I have no prior knowledge of it. I have plugged it in and power tested it as shown in the video. It makes a noise when turned on but this disappears when the tape is playing? I have no ideas why. But that is as far as it has been tested.

May work perfectly fine but as I can’t confirm this need to be sold as listed.

Therefore it is sold as seen with strictly no returns when sold. Please don’t purchase if your not happy with this. Please inspect the photos to see the items condition. No remotes, batteries or separate cables are included in the listing.

Shipping price is to UK mainland only. Anywhere else including Ireland, Northern Ireland, Highlands, Islands etc can cost more so please contact me before purchase.

Happy to ship abroad using eBays international shipping system but please note as well as no returns from a UK address there are strictly no returns from overseas purchases as well on this item.
