The schematic for Philco model D655 (if that's what this is) is in Sams Photofact set 311, folder 12, from the year 1956.
:I have an ac or battery operated portable AM radio. It uses common 1 & 3 volt filament tubes: 3V4,1S5,1U4,1R5. The aluminized sticker near "model" & "serial" says:"D 655-123". This radio has a leather case with a longhorn logo on the back. I cannot find a schematic for this on this website. Does anyone know of one?--thanks
