[AMRadio] OT: Philco model 46-420 Hippo radio in restoration - need help !

[rbethman]

  Howie,

I cannot find the "-125" run code.

All of the Nostalgia air PDFs are either "120" or "121".  Those use the 
"infamous" (Notorious?) 50L6.

is there a "difference" in the pin-out and/or characteristics?

It may even have been "subbed" by a previous owner.
