There is a thread about this on the old forum - don't seem to be able to post a link but a google search on Beomaster rg611 will bring it up! Martin (Dillen on site) will be the expert on this if he is still on site. Good pictures on the link if you scroll down - Beomaster 900 fitted on the one shown . Record player could have been the 42VF with an SP2 cartridge. Very nicely made item - shame about the missing  electronics - I do have a BM 900 at home which is unused - mine is the one called a 900K - have a look at Beocentral under Receivers - can't remember if that is my one or one of Tim's! There is a picture of the 900RG which is the model that took over from the RG611. There are a couple of Beomaster 900 on eBay - will usually need attention! Multicare may also have some, having seen their store room!
