Fw: [HomeBrew] Germanium (Geranium ?)

[windy10605 at juno.com]

I believe you have that backwards ...Germanium is lower which builds up
less heat in a power transistor. The military used them all over the
place.
They were also available earlier along the timeline (process problems ?).

CK722?  Yup, and the 2N107, 2N35, 2N170 ?

Far as I know the general design equations for
transistor circuits apply more or less equally to
Ge and Si, with the significant dif being the Vbe
(.3 - .4 Si, .6 - .7 Ge).  The Transistor Electronics
book by Basil M Taraleshkov (Northrop) has a
lot of specific info.
