Hello -
Please go easy, as this is my first post. I have a nice Philco 46-1226 and I am very confused as to some specifics of the design.
I have the following references:
- Ryder's schematic for -121 model
- Sam's schematic for (???) model
The two differ considerably from what I can see, likely due to the difference in models that they represent...
The problem with the radio initially is that the two 10W power resistors were "open" and non conducting and I am not sure with which values to replace them. Being open, I could not measure them and although they had Philco numbers on them, I am having trouble reading those.
I guess my long-prefaced question is:
What 10W resistors are present in the -125 near the power transformer to form the B+? Or, failing that, is it possible to look up the Philco resistor numbers somehow?
Thank you very much for any assistance.
Matt
