Floor lamp burns out new sockets

Hi folks, first post here. I haven't been able to track down ideas on this one so hopefully this isn't a redundant post. I have a floor lamp, one of a set of three purchased maybe 15 years ago, that I cannot get working. It is a three way turn switch type socket. It started by burning out bulbs far too soon. I replaced the socket and the issue continued - maybe a bulb would last a few hours. I've replaced the socket three times since thinking it was a bad socket, then a batch batch from Home Depot, then today after waiting a few weeks for HD to get some new ones. I've tried different outlets and in fact have a new lamp in the original outlet with no issue. This last socket was a Leviton and when installing I traced the cord to be sure I was putting neutral to silver and cut the cord back to wire the socket with freshly stripped wire. I put in a three way bulb and the arcing was impressive. This socket burned up more quickly and more severely than the previous ones. Now I have replaced sockets several times over the past three decades or so and never saw anything like this. I pulled the cord out and there is no obvious damage such as nicks, pinches, severe bends, nothing. I cannot figure out what is going on here but wondering what others think? Anyone seems a lamp misbehave to such as extent?

Bulbs not the lamp holder was my first thought. Are these regular incandescent not halogen? I'd try a different manufacturer.

I've used multiple bulbs, incandescent, both three way and one. They are a mix of brands and bulbs from those packs work fine in other lamps. It's either the lamp or its me and I can't figure out what else it could be in the lamp.

At this point if it was me and I really wanted to keep the lamp I'd gut it and rewire from scratch just to see if that worked.

How many lamp sockets experienced severe arcing? If just one then it's probably just a bad socket.

If the tab at the socket bottom is flush against the socket bottom, it should be lifted a bit, requires a paper clip with a tiny "J" hook at the end.

Four sockets in total including the original I believe. The last one at least was a Leviton and was purchased a few weeks after the last one.
