Philco 70 rf-coil
#2

Jim

Unless there is data available, the best way is to unwind the coil counting the turns and then see what gauge it is (calipers will do) and wind it using the same or larger gauge (larger is fine as long as it fits in the bobbin).

The reading is not important; what important is the number of turns and, in case of tuned circuit, the length of the winding in total (affects inductance; this is why for this type of coils the gauge should be observed).
Ohms are not really a parameter with coils, it is a parasitic.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
