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

[Howard Weinstein]

Gang 

I have a Philco model 46-420 Hippo radio in restoration. It is a later run model (code 125), using a 50B5 audio output tube, vice a 50L6.  

I'm having some difficulty finding the proper schematic diagram, Yeah, I know, I shouldn't even need one, but, this  unit has an inoperative 1st audio stage and I'm seeing some  " wiring strangeness "  in that area.   

Also, the filaments are not wired in series, which I find highly strange.  I am have been searching the web, but, cannot find a schematic for this specific 46-420 code 125 Philco "Hippo" AM radio.  

Can ANYONE assist me in finding this schematic !
