Neutralization of a Philco 87
#3

I think the trimmer is good, but should I swap it for another one to see if the problem moves?  Number 2 for number 1? I’m 99.44% sure I’m adjusting the correct trimmer. I had to rewind the primaries of the other three coils but this one was good. One thing I wondered about at the time was that the primary of this coil has probably twice as many turns as the other three. Might this have something to do with my problem?
Thanks again.
