Please can anyone tell me what my 1970's collection of Bang and Olufsen music equipment is worth? I have a Beomaster 2400 with original remote control, A Beocord 1500 Tape Cassette Player and a Beogram RX2 Record Player. They all match and are all in original condition with cabels and plugs etc.

My experience has been that old audio equipment is like old computer equipment. Typically valueless, except in the case of the few who target that brand or type for collection.

It's like my two Atari ST computers. They usually go for very little on eBay, but occasionally a collector comes along and pays decent bucks for one.

eBay is a good resource to gauge value. Find some similar items and put them on your watch list so that you can see what they sold for at the end of the auction.
