I.F. Transformer rewind help.
#1

Good Morning All,

The 38-93 that I am working on has a bad primary winding on the #2 I.F. Transformer (#32-2459).
My question(s) would be; is there a simple formula to calculate the length of wire required for re-winding ? According to the schematic there should be 17 Ohms across the primary. I have a spool of #38 wire.
I made a mess of the coil unwinding it, so I don’t know the original number of turns. Can length of wire alone be used to determine the finished coil without taking the number of turns into consideration?
Does the width/height of the finished coil matter as long as there is 17 Ohms of resistance?
Thanks in advance.
