Recommendation for Yamaha CR2020 service

[Jazzismylife]

Hi, Newbie here.

I am looking for a recommendation for a company or individual who can do the service bulletins on a Yamaha CR2020 receiver in the UK please.

I hear that they are notoriously difficult to work on, plus it is cosmetically perfect, so I'm concerned to find someone reputable who will treat it with respect.

Any help would be gratefully received, thank you!
