They are all Si transistors. Ge have Vbe around 0.3 to 0.4V, I have quite
a few devices with Ge transistors.

I can't imagine what Si tr would have 0.8v V_be or why. Do you know?

Geraniums start much lower of course, but also rise higher quickly as current increases. 0.8v on a Ge junction is no cause for surprise.

The ME tr you mentioned is a Si device, so I'm puzzled by its V_be.
