      Dave, this Deja-Vu trip back to my youth is much appreciated, it made me
      dig out my old M9 Spaceview as well as my dad’s M6 out of storage and
      gave me pause to remember the good old days……

      Back in the days before high speed video, I remember watching the tuning fork movement using a strobe light……

      BTW,
      my understanding about the transistor change was driven by sensitivity
      to ambient heat, the original behaved erratically in desert environments
      and temperatures on the order of 130 deg F……

      Another BTW, you get a *pass* for so horribly mispronouncing US slang words like *Bulova* & *Speidel*…..

      Thanks for the memories,

      FJP
