3-500z's Pin Resoldering

Getting a good pair of tubes has been difficult. Two arrived broken from Canada. Today one more (out of a matched pair) arrived from OK broken and the other one looks to be knocked off center some. On a positive note two that I thought had bad filaments survived the CQ WW contest after having the all the pins cleaned with 80 grit sandpaper and resoldered. They are putting out a lot of power!
