Ebay is the best place to sell if you want it seen by the biggest audience, hence you will have a higher chance of selling it, some test gear from the 60's, 70's & later can go for a good price on there.
The local auctions & club auctions will have far fewer people seeing items, especially if they don't have online bidding.
Even stuff that looks like it shouldn't sell does so eventually, this HP 3722A with stuff growing in it is one example.
I've bought a drowned HP item myself that became a foot & side frame donor.
