OK here is how I would wire to the gram socket on a vintage radio.
The resistor values R1a & b can be found by experimentation, but I would start off with 2.2k for each, if the volume is too much then increase to 4.7k or 10k.
R2a & b are optional if the signal is still too loud at normal volume setting on the radio. but you could try 4.7k for both.

Or you could substitute a 10k trimmer for the R2 resistors.
You will probably ideally want the iPod volume to be set to normal for earphones.
