Loose tube sockets


I'm re-tubing my amp with new 6550C's. They are the same style tube I took out. But when I put the new ones in they fit very loose in the socket. The old tubes were nice and tight. I would think the new tube would be the same size and fit as tight.

What's going on?

Newbee,

These are SED SV6550C's the same as the ones I took out.
I put the old tubes back in and they fit like they should, tight. The pins on the new tubes must be smaller. Re-tensioning the tube sockets maybe the thing to do.
