Must admit, looking at it, I'm thinking "the amp, yep, the rest...?". £200 seems steep for what you get here. Great if you collect the stuff, hard to find all of that gear in decent nick (assuming it is) but the price is high:-
Equalizer - £20, but do you really need it?
Tape deck - £20, same as above
Amp - £60 - yep, good amp, but this is the most you ought to pay.
Speakers - £hmmmm - debatable
Marantz CDP - seen these go for £20 on Gumtree
For a job lot, I'd take them off his hands for £120 tops. £200 and auctioned off is keen, but he's got a bid so good luck to him.
