As to the de-soldered pins .. RF Parts .. no pins to replace pitted ones...
anyone have a few spare 3-500 pins I could get for a good friend of mine
(WA6RTP) who is bothered by his pitted pins as result of his Hank 2K3 doing
a de-solder job .. .. he not being computer guy .. glad to send SASE,
whatever -- the amp works, but .. he wants to make sure the pits don't
cause further problems. .. 73

I have seen this problem myself. The problem is that once the pin and
the contact start getting hot, the spring loses its temper, which
increases the contact resistance, making the problem worse. Ultimately
the solder in the tube pin melts.
