You might want to look at the Bluebook values here on Agon. Most of the pieces you have are pretty rarely seen and/or sold here, but it might be a good start.
Help ? I don't want to get ripped off
I'm trying to sell some audio equipment for my grandpa. I don't know enough about the equipment to really stand by an asking price. I have researched each of the items, but pricing for some seems random and prices for others is unavailable. I have found a place that will buy them, but I don't want to get ripped off. I understand they have to make a profit, but I don't want to get totally "taken". I have listed the items below. Any pricing help would be greatly appreciated.
