Use a pick tool, needle file or something the same size of the tube pins & gently push it straight down into each opening of the socket. That should help loosen it up some. DO NOT USE ANYTHING LARGER THAN THE TUBE PIN!!! It will make things too loose which will cause arcing & carbon deposits and cause a whole new set of problems. You can also try using a fine grit sandpaper on the tube pins if they look dull.
