Philco 84 code 121 no sound
#39

Before I start on the oscillator coil....are the number of turns and direction of those turns more important than the finished coil resistance?

The reason I ask this is the feedback winding has fewer coils (14-1/2 turns) than the antenna primary did and the resistance on the feedback coil is 2.3 ohms now. Once finally terminated the antenna coil came to about 2.3 ohms but has more turns. Both coil forms are the same diameter and I'm using 34ga. wire. Granted there is some corrosion on the feedback coil, but I do not have a reference for a resistance reading on this coil.

Am I over thinking this?
