Does one tweeter field coil on your Philco 38-690, or ones you have worked on, run much hotter than the other? I was working on the alignment after cleaning the chassis today and noticed this. I found that it is the tweeter field coil which carries the current which goes through the main speaker field coil to ground. What do you think?
