   Thanks for the update to what you found and likely repaired. If you   
   were to quit posting right now, in a few years or less I'd be hard   
   pressed to remember your name. But that little fix you made will be   
   stuck in my head till dementia kicks it out😆️

   ---------------------------------------   
   It was visible because I used a powerful Optivisor headband magnifier (a   
   recent flea market treasure) and soldered for a living so I know what a bad   
   or failed  joint looks like. Instead of flowing smoothly onto the pin the   
   solder was peeled back very slightly at the intersection with the pin, as   
   though 25 years of thermal cycling had torn it loose. The break was visible   
   as a hairline gap in what should have been a continuous light bulb   
   reflection along the fillet/meniscus.   
      
   Maybe a posting here will find its way to a special interest group that can   
   use it.   
      
   In a few years I may be hard pressed to remember my name. I've already   
   forgotten my birthdays though that doesn't seem to stop them.
