Motorola Schematic

Where would I look for the circuit diagram for a Motorola A15J-3? It's a 1958 plastic table radio on a PCB, very basic 5 tuber. I need the values for couple of toasted resistors. thanks.

Sir Neal. . . . . .


. I need the values for couple of toasted resistors. thanks.



Initial hint . . . probably not the 3.3 or 6.8 meg units . . . heh . . heh . . heh .


For overheated carbon composition units with massive color coding degradation, the primary candied dates


would be the [YELLOW] marked up units, unless an IF tube flashed its cathode resistor.

Pee Ess I see I didn't quite include C6A in my RED + highlighting.
