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! On 5/12/2014 10:58 AM, Poul Erik Karlshøj (PKA) wr

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
