Rapid changes from warm areas on the ground to cold areas at high altitudes can place stresses on electronics involving thermal coefficients of expansion. I couldn’t believe I couldn’t find these items locally – no Radio Shack that I called carried either the germanium diodes or the earphone and the few electronics shops I called carried the earphone but it was $10.00 and no germanium diodes. The challenge in most designs is getting that excess heat away fast enough and far enough so that the source remains sufficiently cool.
