Advice on pricing old Audio Research pieces


Hello

I'm looking for help with pricing for a Audio Research SP6 pre amp and a D52B power amp. They are both from 1979. Any ideas?
I'm not into spending $20 to find 2 prices...

OK thanks for the comments- I see your point about the blue book- I don't anticipate using it much but you're right....
