[Elecraft] KPA500 ser. no.1066 factory built, Loose diode 1N5408

[Vic Rosenthal K2VCO]

The diode is probably not defective (although the soldering is). Unless 
your DVM measures the forward voltage drop of the diode, resistance 
readings in the forward direction are probably unreliable.
I would just resolder it and see if it works!
