Well, if it does not well, I or someone else will gladly contribute a ceramic socket to replace. You're going to be quick and fast to do a solder joint. Of course remove the tube. Like have everything ready and make a good mechanical connection first maybe use a little rosin flux and zoom in with freshly tinned and blobbed and hot iron and zap some narrow guage 60/40 or better and leave it cool for a while. You don't usually get a re-do on these things.

Post the chassis hole size and riveit spacing and orientation of pins if you need a spare socket. One of us will give you one.
