Get another BG 5000 or the tangential tracking 5005 (or 5500):                                                                      

-They both were originally sold with the Beosystem 5000 and match it perfectly

-They both will operate by remote control as part of the system

-They're both virtually always available on eBay

Do you still have all parts of the tonearm? If so, it's an easy fix. Been there, done that. Several times. 

Thanks for the replies lads, I'll be keeping an eye open for one on Ebay. I may have a go at repairing this one as I have all the parts but the bit at the end that the stylus plugs into has snapped also, I might have to drill out the shelac a bit to get enough wire exposed to solder to🤔. If I can get hold of a second hand part or a knacked t/table it might be easier. Thanks again for the info and advice I'll let you know how I get on. Cheers.😁 

Two questions:

Is the tonearm of the 5000 the same as the RX 2?

Are you in the States?

I bought an RX 2 tonearm a month or so ago.  I was going to use it for something of an art project with my kids, but would consider selling it to someone who wants to restore an otherwise working table.

Hi Rich, It does seem to be the same arm as the RX2, I'm in Manchester, England,uk I don't think shipping wouldn't be much so yes I would be interested. If you could pm me with you price. Cheers
