Found this list here.
By and large the surplus business in the US is small operations and one person shops. Probably a lot of them have disappeared in the recent economy unfortunately as their source of supply and customer bases dried up. I’ve used none of these places and Don’t know how good the service is. This list is for reference only. I’m just going down the list to see of the websites work.
Website “under construction.”
Looks like owner is selling old stock and retiring.
Advanced Component Electronics.
Looks like a good place for old radio.
California Electronic Surplus.
Site replaced by Chinese blog.
Dan’s Small parts.
Fair Radio Sales.
Halted Electronic Supply.
JDR Computer Products.
I’ve heard about this place for some time. Thought it had died. Apparently not.
Martin P Jones.
Not Just electronics. Looks like they sell all sorts of stuff that a business might need.
Oak Hills Research.
Playthings of the past.
Surplus Sales Of Nebraska.
Save this one. Test gear is EXPENSIVE and it lasts forever. There’s nothing wrong with getting used.
Weird Stuff Warehouse.
The front page didn’t look all that weird to me. But I’ve dealt with some VERY weird projects in the past. Anyway, this list is another source for getting hardware for hacks and functional prototypes as well things like test gear and stuff for experiments and tooling.
