Do I need to replace tube socket in my amp?

So I previously started a discussion "Did I just ruin my amp". I thought everything was good and that I just needed to replace the power tubes but recently I have been hearing some crackling coming from my speakers. When I took out the tubes I noticed what looks like melted metal bridging two of the pin sockets which also looked burned. I assume this is what is making the tube sound like crap. If I am correct anyone know where I can get this fixed in LA and approx costs? By the way the amp is a used Melody el34. Thanks.
