Has anyone ever owned and heard the last version? I read it is a push-pull that they put back in it - rare. 

Brobertson, I have a late version 90. It is a very good sounding radio, maybe because the speaker has been re-coned. Here you can read about the restoration   Philco 90 Restoration (philcoradio.com)      

The mid version is the most common, followed by the early version, the late version is the least common of all.
