Umm... the diodes don't quite pop out in a jiffy. You must first tear
apart the instrument just to get to the diodes. They're tiny little

They're the 4 black things labeled "COB". If you order some from
Digikey or Mouser, be sure to get plenty of spares. I dropped two on
my workbench, where they promptly disappeared.
