Get a dental tool or strong jewelers screwdrivers and coax the tube sockets back into their original round shape, or as close to it as you can. Be patient and persistent. Finish with deoxit on sockets and pins - squirt, wait a few seconds, then squirt again. Pay special attention to the grid connections.
Removing sockets requires enormous patience if the sockets are soldered onto PCBs. There is always that last bit of solder that doesn't want to come off, and the tight fit makes it harder to do. I did it once and will never do it again.
It's always a good idea to check the cathode resistors after any failure. Some manufacturers use them as backup fuses of a sort.
You can also get tiny wire brushes to help clean the output tube sockets as well. I think jbtools.com has them.
