[Amps] Chinese sockets

[Pete Smith N4ZR]

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.
