RS130 hums like a bee swarm (Transformer)

Dear Rose Team,
my unit hums like a bee swarm in operation; source is definitely the transformer.
I sent it back to the dealer, they checked if transformer is fit tight, and send it back to me telling me it should be OK and they won´t help any further in this topic. There is no DC in the line due to a huge DC Blocker.
When i start up the device, the surface noise raises from 35dB to 44db; and thats quite noticeable on listening position, its the loudest device, even the amplifier is dead-silent (McIntosh MA12000)
Question: can you sell me a quiet transformer so that i can swap it?
Thanks in advance

I have forwarded your symptoms to our hardware team.

They responded that the problem appears to be with the transformer inside the RS130.
Contact the distributor in the country where you purchased the RS130, describe your symptoms, and have them replace the transformer in your RS130.

@Rosehan
Thank you for the fast reply.
I already sent the RS130 to my distributor.
They checked and said that it is OK within given parameters, and refuse further action.
For me its not OK if i hear the device huming at my listening position.
Is it possible to buy a transformer from Hifi Rose directly?
If not it´s also OK, if you could provide the transformers distributor, i could also oder there.
Fine with further communication per PN if needed.
Thx

Mine buzzes a little and seems to be affected by other mains items

We are unable to ship transformers to individual customers.
Repairs and replacement of parts are the responsibility of our distributors in each country.
