K3 PA supply Gold Pins

Mike Harris-9

After nine years the dreaded "ERR 12V" struck. Possibly brought about by
my increasing use of high duty cycle RTTY and FT8. Normally I'm S&P so
the high current pins don't usually see much heating time.

The whole job on #00345 took about three hours of patient progress,
dismantle, repair and rebuild. Interestingly only the pins on the RF
board were toasted and not those on the PA module which looked as good
as new. I ended up replacing the two sets of six pins, one set a clear
necessity and one set precautionary and one damaged female connector.

The most annoying thing about the whole job were the TMP coax connectors.
