Yes, I'm a reseller. I bought a large collection of them from a pawn shop that was closing. Some of them are quite sought after. The most expensive I've sold were $200/ea. Some sellers use higher end testers in order to make claims that the tubes are "matched" in their percentage of specification from new. I think it's a dubious claim. I have a cheaper tester that says if they're good or not. I only state that they are tested and appear to be new since I obviously have no way to know if they actually are NOS or if someone used them at some point.
