Philco 80 open coils
#4

Thanks for the welcomes, been on here often searching for info but guess I never joined (thought I had) until now.

Anyhow...so I have previously re wound the osc coil in my 1936 ish Philco 60. There was a LOT of info on that one in here and online but not much if anything on this little 80. I bought and used some 38gauge for the 60 as Ron recommended on this site. It worked well.

So last night I used that enameled 38gauge to do the open antenna coil. Did it just like original, same winding direction, turns and plastic insulator cut outs ect. My only concern is my DC resistance measured 3.5 ohms and the schematic called for 2.66. Should this make any difference?

Does anyone know the physics of winding coils? For instance would a coil with 17 turns of 38g wire have more or less resistance then a coil with 17 turns of 36g wire? I was just curious if one could experiment and get the correct DC resistance.

Thanks
