Hi All;
Can anyone tell me WHY the Primary coil of the RF transformer has a 10K Resistor accross it ?? The primary coil measures 38.6 ohms and the secondary coil measures 4.6 ohms.. The Primary coil is wound inside of the coil form in that cross hatch type of winding.. The Secondary coil is wound on the outside of the coil form..
The other set that has the same type of Mixer Tube 1C6, a Philco 39, which is a two band set against this which is a four band set.. The circuit is easier to follow on the two band set, and it looks like the Oscillator circuit is the same between the two, except that one is a four band set and the other a two band set..
THANK YOU Marty
