It is a 45V, 10A, 90W PNP Audio Output TO3 GERMANIUM transistor.
At least NTE121 and 68P1B is something like.
... See attached data ....
The hFE gain is good: 50-165, typ 90
VBE at 1A is only 0.38V ... which is a Germanium feature
fT, upper transistion frequency is low: 300 kHz
but this enough to make a good output follower stage

I am sure someone would like to try those.
Always nice to explore nice things. New challenges.
We have had several threads about old Germanium devices.
