Link to an up coming auction which may be of interest to some ( first dozen lots or so ). I have no idea of the value of vintage audio equipment. The estimated prices for the ACT pre-amp, Linn LP12 TT and especially, the ATC tri-amplifier speakers (7000 - 8000GBP) would indicate there will be interest by collectors/audiophiles.
