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!

We have found a loose (de-soldered) diode 1N5408 in this factory
assembled KPA500. The diode shows >10Mohm in one direction and 2-3
Mohm (varying) in the other direction (DVM) Where is this diode
located (if there are several, then where?), what is its function and
is it replaceable by a skilled tech person? What could be the reason
for the failure - it does not appear to have been over-heated, so
desoldering appears not logical.
Is there a diagram of the KPA500 available?
