KEF 104.2 and B&K ST-202

Need your advice. I am finally giving-up my 104.2's and a B&K ST-202 amp. The KEF components are perfect, though the top of the cabinets need to be restained. The B&K is excellent. Any idea as to what a fair price might be for either one? Speakers are 1992 (?)and B&K 1990.
The 104/2 The price is dependent on condition of cabinet and drivers.The cabinets can always be easily touched up but the drivers are always the important ingrediant...If the drivers are in top shape ( don't need to be reconed etc..) my guess is they are worth $500-$700
Yep, there is a pair on eBay for $520 as is.
