One trick that I have used here on some 35-year-old sockets is to swap
two of the springs from the grid pins with the ones for the filaments.
I think it was W8JI who first pointed out here that resistive heating in
the filament pins could be responsible for loss of temper in the springs.

They are often cheaper than used Johnson sockets. The problem with
used ones is that often the springs are no good.
