Thanks Otto for the idea!! Excellent!!
Just to confirm, you are suggesting that I use the Philips transformer the otherway around, i.e. apply the input (6.3V) to the secondary and then the output will measure the different voltages on the selector. Is that what you mean?

This will really help to determine which wire carries which voltage but, what about the other pins on the Voltage Selector (next to the round black knob). I would like to know what these were connnetced to in the original radio design? Any insight??

Thanks again,

>Hello Ahmed,
>I think the easiest way to find out the proper connections is, taking a second known radio transformer, and then connecting the 6.3 filament winding to the 6.3 filament winding of your Philips transformer. When you apply the proper power to the known transformer, you can measure the voltages of the Philips one. The voltages should correspond with the voltages on the selector (due to losses in the transforemer you will probalbly measure lower voltages, but that should not be a problem).
